There are 21 routes assigned to the "G" zone of the California Route Marker Program, which designates county routes in California. The "G" zone includes county highways in Monterey, San Benito, San Luis Obispo, Santa Clara, and Santa Cruz counties. Santa Clara County is the only county in California that operates a comprehensive system of urban expressways.[1]


County Road G1

LocationSan Benito County
Length5.42 mi[2] (8.72 km)

County Route G1 (CR G1) is a road in San Benito County, California, United States, providing access to Fremont Peak State Park from State Route 156 in San Juan Bautista. It is signed as San Juan Canyon Road for almost the entire length except for a small portion of The Alameda.

Route description

From the southern end of G1 on Fremont Peak as San Juan Canyon Road, G1 begins a steep, sharp-curved winding descent from around 3,000 feet for the first 2 miles, north to northeast. G1 then curves to the west for about 2 miles before turning north. At the intersection of Mission Vineyard Road, G1 becomes The Alameda, which then heads north for approximately 1/4 mile before reaching the northern terminus at State Route 156. Beyond the northern terminus, The Alameda continues into downtown San Juan Bautista for 0.2 miles until the intersection of First Street.

County Road G2

LocationSanta Clara County
Length9.7 mi (15.6 km)

County Route G2 (CR G2), more commonly known as Lawrence Expressway and Quito Road, is a busy 9.7-mile (15.6 km) long north–south link through Silicon Valley in Northern California. The majority of G2 is part of the Santa Clara County expressway system.

Route description

Intersection of Lawrence Expressway and Prospect Road in San Jose, California

G2 runs from the Quito Road overcrossing of SR 85 in Saratoga, north along Quito Road. G2 is not signed along this section and is not commonly recognized as existing along this 2 lane road by either locals or mapmakers. The Quito Road portion is also maintained by the City of Saratoga rather than Santa Clara County.[3]

As the road leaves Saratoga and enters San Jose, it widens to a 6 lane county-maintained expressway with a concrete island divider; at this point it becomes Lawrence Expressway. The Lawrence Expressway section from just south of Saratoga Avenue is more readily recognized as G2. Local residents almost exclusively refer to G2 as Lawrence Expressway. The road continues north, with access usually restricted to major intersections which are controlled via traffic lights.

Lawrence Expressway continues northeasterly and junctions with I-280 and Stevens Creek Boulevard over a complex shared separated grade crossing. Lawrence Expressway proceeds under I-280 before immediately rising over Stevens Creek Boulevard. San Tomas Expressway and Campbell Avenue also share ramps for access to I-280 with the exception of the onramp to Southbound I-280 which is accessed directly from Lawrence Expressway, a frequent cause of confusion for drivers on Stevens Creek Boulevard wishing to access I-280 due to unclear signage. Lawrence Expressway continues north into Santa Clara and widens to 8 lanes with an HOV lane occupying the far right lane.

Lawrence (looking south, center) at Central Expressway

Lawrence Expressway also has another separated grade interchange with El Camino Real (SR 82). Lawrence Expressway then enters Sunnyvale. At this point the expressway passes over Caltrain's Lawrence Station. Lawrence Expressway also passes under Central Expressway (G6) on a separated grade interchange and over US 101 on a separated grade interchange. The US 101 interchange was upgraded in the early 2000s to include traffic light control on G2.

G2 reaches its northern terminus at the end of Lawrence Expressway at the SR 237 Freeway. The physical road continues north as Caribbean Drive, which then curves back south through Sunnyvale and Cupertino, paralleling Lawrence Expressway under several different street names until the roads intersect again at Highway 9 and Quito. This effectively makes the road one continuous counterclockwise loop through the Santa Clara Valley, where one driver could start on Quito road and end up exactly where they started without ever changing lanes.


The designation G2 existed to the 1950s. The route replaced what was originally called Lawrence Station Road (after the Southern Pacific Lawrence station), from Mountain View–Alviso Road in the north to Stevens Creek Blvd. on the south, roughly paralleling Saratoga Creek. Lawrence Station was itself named for Alfred Chester Lawrence.[4] Crossing Stevens Creek, the route was originally called Doyle Road, a small two lane road up to the point the current Doyle Road exits to the east. The section between Doyle and Saratoga Avenue at Quito Road was originally orchards.[5]

G2 was first signed as a Santa Clara County Route in 1962 as construction was completing on sections of the upgrade to an expressway. County Route G2 was originally planned to link up with SR 85 when it was built. At the time of G2's inception SR 85 was in the early planning stages and an interchange had been envisioned at Quito Road. However opposition to the freeway was intense in Saratoga and the planned interchange between SR 85 and G2 along with an interchange further north at Prospect Road were abandoned in favor of the existing Saratoga Avenue interchange. G2 is unsigned from SR 85 to Saratoga Avenue along Quito Road. North of Saratoga Avenue, Lawrence Expressway is currently signed as G2.[6]

In the 1990s Lawrence Expressway was widened north of I-280 to 8 lanes to accommodate an HOV carpool lane.

As of 2019, Santa Clara County is planning a major grade separation project at Homestead Road. This will be one of the largest expressway improvement projects in many years.[7]

Animation of USGS maps of 1953, 1961, 1969, 1974, and 2015, showing the conversion of Oregon Avenue to Oregon Expressway, and its interchange with Alma Street and connection to Page Mill Road. In 1953, Oregon Avenue had a T intersection with Alma Street, while Page Mill Road and California Avenue had level crossings across the Southern Pacific railroad tracks. By 1961, the left-jog underpass connection between Page Mill Road and Oregon Avenue had been made, but Oregon was still a narrow residential street, which connected to US-101 so it became a very busy route to Stanford and the Stanford Industrial Park. By 1969, the Oregon Expressway had replaced about 90 homes on the south side of Oregon Avenue. By 1974, more ramps were added to the Alma Street interchange. At some point, by 2015, the railroad tracks behind the Sutter Packing Company cannery / Maximart / Fry's building were gone (where the 2015 map says "Mayfield"); this was the track that connected the Peninsular Railway route that ran along what became Foothill Expressway.

County Route G3 (CR G3), more commonly known as Page Mill Road and Oregon Expressway, is a short 4.5-mile (7.2 km) northeast–southwest arterial route that spans the lower peninsula region of the San Francisco Bay Area from I-280 to US 101. G3 runs through Palo Alto and unincorporated Stanford University lands. It is part of the Santa Clara County expressway system.

Route description

Page Mill Road heading downhill toward Hanover Street and El Camino Real
Oregon Expressway where it goes under Park Blvd., the Caltrain tracks, and Alma Street (which is also the start of G6)

CR G3 begins in the west at its interchange with I-280, at the Los Altos Hills–Stanford border. It proceeds northeast as a four lane expressway over the rolling hills of Stanford University until it reaches Foothill Expressway (G5), at which it has an at-grade intersection. East of Foothill Expressway, G3 descends down into the more urban areas of the lower peninsula, going through the industrialized area of the Stanford Research Park located in Palo Alto. The road along this section has a reduced speed limit and several turnoffs along its length until it reaches El Camino Real (SR 82).

After SR 82, G3 branches from Page Mill Road (which becomes a narrow access road to the California Avenue Station), and curves under the Caltrain tracks, continuing as Oregon Expressway for the remainder of its northeastward journey. Oregon Expressway functions more comparably to a County-maintained Arterial Road for Palo Alto, with frequent signaled intersections and a posted speed limit of 35 MPH. G3 reaches its eastern terminus at its junction with US 101, where it shares an interchange with Embarcadero Road.

Page Mill Road (no longer designated G3) continues southwest of I-280 for 6 miles (9.7 km), a twisting two-lane road that climbs to Skyline Boulevard (SR 35) at the crest of the Santa Cruz Mountains. It passes the entrance to Palo Alto's Foothills Park, and the Monte Bello and Los Trancos Open Space Preserves. Under the name West Alpine Road, the road descends west of Skyline Boulevard to a turn-off that leads to Portola Redwoods State Park, where the original Page sawmill was located. Other than a commemorative sign, no artifacts remain at the mill site, which is accessible only by Slate Creek Trail from either Portola Redwoods state park or from Skyline Boulevard (SR 35).


This route was designated in 1962. G3 is currently signed its entire length. Page Mill Road was originally known as Mayfield–Pescadero Road,[8] but only the urbanized portion of Page Mill Road is part of G3.

The widening of Oregon Avenue from a congested narrow residential street to a median-divided 4-lane Oregon Expressway was narrowly approved by Palo Alto voters in a June 5, 1962, election; about 90 homes on the south side of Oregon Avenue were moved or destroyed to make room for it.[9] The original Oregon Ave still exists on the north side of the roadway, though is mostly separated from G3 with trees and shrubbery.

Due to the steep grade and high water table around the area of the Caltrain underpass, the underpass is notorious for flooding during heavy rains, which often overwhelmed the county pumps which were installed due to the existence of a Superfund site 1/4 mile upstream on Page Mill road.[10] When the underpass is closed due to flooding, through traffic must detour onto Alma Street (Route G6) and cross the train tracks at either Churchill Ave to the North, or Charleston Rd to the south.

When Interstate 280 was completed through the area in 1969, the old narrow Page Mill road, which passed by the Frenchman's Tower, was bypassed over the hills to the south and expanded to 5 lanes from 2. The old road was renamed "Old Page Mill Road", the center line was removed, and car access was limited to eastbound and local traffic only. The road is still traversable today and is a popular route for bicyclists.

In 2014, the county began a rehabilitation project on Oregon Expressway, which entailed rebuilding and landscaping of the center median, installation of new traffic lights and mast arms, and repaving of the travel lanes. The intersection of Ross and Oregon, previously an uncontrolled intersection, had new traffic signals and sensors installed and Ross was converted into a Bike Boulevard.

County Road G4

LocationSanta Clara County
Length14.11 mi[2] (22.71 km)

County Route G4 (CR G4), more commonly referred to as San Tomas Expressway and Montague Expressway is a busy 14.5-mile (23.34 km) long link across Silicon Valley. G4 is part of the Santa Clara County expressway system.

Route description

Intersection of San Tomas Expressway and Monroe Street in Santa Clara, California

CR G4 begins in the south at its interchange with SR 17 and Camden Avenue as San Tomas Expressway in the city of Campbell. The road is three lanes wide in each direction, with an HOV carpool lane occupying the right lane, from SR 17 north to Homestead Road, where it expands to four lanes in each direction with an HOV lane until San Tomas "ends" at US 101. The majority of intersections along San Tomas are at grade, controlled by traffic lights. The only grade-separated intersections along San Tomas are at SR 17, US 101, Winchester (necessary due to a Union Pacific branchline), and the junction with Central Expressway (G6). G4 intersects at grade with El Camino Real in Santa Clara. Further north in Santa Clara, G4 crosses US 101 and becomes Montague Expressway.

Montague Expressway is signed as an east–west route, however it is not signed as G4 along its entire length. Montague continues east as an 8 lane road until it crosses Interstate 880 on the San Jose/Milpitas city line, where it loses a lane to become a 6 lane road. G4 reaches its eastern terminus at Interstate 680 but the physical road continues as Landess Ave further east until it ends at its intersection with Piedmont Road.

G4 was designated and signed in 1962 along the San Tomas portions. Montague was designated later around 1978. Whether this has anything to do with Montague and not being physically signed as G4 is uncertain. Emergency Call boxes along Montague however are labeled as being on G4 leaving no doubt that Montague is part of G4.

Original plans called for G4 to include Hillsdale Avenue and Camden Avenue, between its present-day southern terminus and the southern terminus of Capitol Expressway (G21). These plans were never brought to fruition.

County Route G5, more often referred to as Foothill Expressway, is a 4 lane, 7.24-mile (11.65 km) long, northwest–southeast route in Santa Clara County. G5 connects Palo Alto, California to the Silicon Valley proper closely paralleling I-280 through the lower Santa Cruz Mountains foothills. This route is part of the Santa Clara County expressway system. The speed limit for much of Foothill Expressway is 45 mph.

Route description

G5 begins at its southeastern end at I-280 in Cupertino, California. It proceeds northwest directly east of I-280 making it a viable alternative route for short trips between Cupertino and Palo Alto. The road is a four-lane expressway along its entire route. Access is generally limited to major intersections that are governed by traffic lights except for an interchange at Fremont Avenue, which the interchange also provides access to Miramonte Avenue and Loyola Drive. G5 travels through several affluent neighborhoods in Los Altos before reaching its northern terminus at the intersection with Page Mill Road (G3). The physical road continues north as Junipero Serra Boulevard and passes the back entrances to Stanford University. In the south, the road continues past Foothill Blvd onto Stevens Canyon Rd, a winding mountain road that passes by a rock quarry and several open space preserves.

Foothill Expressway (left and center) at Grant Road and Homestead Road (right)


G5 was designated in 1962 and is currently signed its entire length. The route was built upon the right-of-way for the Los Altos branch of the Peninsular Railway. The buildings along the route at Loyola Corners in Los Altos are historical railroad station buildings.

In 1970 one of the first scientifically designed noise barriers in the nation was conceived for Foothill Expressway in a study overseen by the Santa Clara County Public Works Department using Sunnyvale consultant ESL Inc.

In 2021 Route G5 saw one of its only major expansions from since it was first built; the section of Foothill between San Antonio Rd and El Monte Avenue was widened from 4 lanes to 6, complete with removal of the dedicated right-turn ramps and installation of new traffic signals. This section of G5 often sees heavy commuter traffic, particularly from motorists accessing I-280 from San Antonio road via El Monte.

County Route G6, which comprises Central Expressway and part of Alma Street in Palo Alto is signed as a 12.3-mile (19.8 km) long, east–west route in the western portion of Silicon Valley, California. While paralleling US 101, El Camino Real (SR 82) and I-280, all of which are signed north–south, Central Expressway is signed east–west. This is due to the fact that all of these routes move in an east–west direction in this area, but these other routes continue longer than Central Expressway and are mostly north–south overall. This route is part of the Santa Clara County expressway system.

Route description

Route G6 actually begins in the west at Oregon Expressway as Alma Street in Palo Alto. In Palo Alto, G6 remains a major surface street with four lanes of traffic and a center turning lane to service the many driveways and turnoffs available. At the Palo Alto – Mountain View border at San Antonio Road, G6's character changes, removing the driveways and frequent intersections and adding a center divider, and is renamed Central Expressway. Central continues east as a 4-6 lane road through the city of Mountain View. There are signalized intersections at major thoroughfares, and there is a grade crossing for the VTA Light Rail. This section's intersections are primarily at-grade with cross streets controlled by traffic lights, although there are some overpasses, such as for San Antonio Rd, Shoreline Blvd, SR 85, Whisman Rd, SR 237, and Middlefield Rd.

Up to this point, the roadway has paralleled the Caltrain rail line all the way from the Palo Alto station, which limits the intersections on the south side of the road. The roadway branches off from the railway at Bernardo Ave.

After crossing under SR 85, Central Expressway takes on a very freeway-like appearance (which is not typical for most county roads) for several miles through Sunnyvale. Through this section Central Expressway has a wide center divider and a sequence of several separated grade interchanges with main cross streets and no turnoffs or driveways. The final in this sequence is at Lawrence Expressway. East of Lawrence Expressway, Central Expressway resumes at grade intersections along with sporadic HOV lanes at the approaches to intersections. Central has one final separated grade interchange with San Tomas Expressway. Route G6 makes a turn onto De La Cruz for a few hundred feet until it reaches its terminus at US 101, just outside the north end of San Jose International Airport. The physical road continues as De La Cruz Blvd/Trimble Rd towards Route G4, while at its western terminus in Palo Alto, Alma Street continues northeast through downtown Palo Alto until Alma St ends at El Camino Real near the border of Palo Alto and Menlo Park.


Central Expressway was first designated in 1962. Central Expressway was a vital route through the western Silicon Valley in the days before US 101 had been widened and I-280 had been built as an alternate route. Central Expressway still acts as an alternate route to US 101 through the west valley, however usage has declined as both freeways are now much larger and more direct routes.

In 1982, the prohibition against bicyclists using Central Expressway's shoulders was lifted. All pedestrian prohibitions were repealed by 2003.

In 2007, construction was completed near the eastern terminus widening Central Expressway to accommodate an HOV lane and a reconfiguration of the intersection with Lafayette Street.

In 2016, VTA expanded the Central Expressway grade crossing from 1 track to 2 tracks, necessitating some closures between Whisman and Mary for construction. Route G6 was also closed to vehicular traffic in the same stretch on the day of Super Bowl 50 so that Light Rail traffic would have priority to Levi's Stadium.[11]

In 2020, Mountain View closed Castro Street to vehicular traffic to support outdoor dining in the wake of the COVID-19 pandemic. The road is still closed to this day, and the turn pockets onto Castro Street from Central remain coned off while the city and county determine more permanent plans for this intersection.

In early 2023, the eastern terminus of G6 was modified to match the new configuration of the De La Cruz Blvd / US-101 interchange. The right slip ramps to/from De La Cruz on Central were permanently closed to traffic and replaced with standard right turn lanes.

Central Expressway is currently signed as G6 sporadically along its entire length.

Length3.25 mi[2] (5.23 km)

County Route G7 (CR G7) is a road in Santa Clara County, California, United States, southeast of Gilroy. The road is known as Bloomfield Avenue for its entire length, which runs from State Route 25 near US 101 to State Route 152.

The route serves as a bypass for travelers who are traveling from westbound State Route 152 to southbound U.S. Route 101. County Route G7 bypasses the State Route 152 at U.S. Route 101 interchange, where State Route 152 is signed as 10th Street. This bypass avoids considerable amounts of traffic congestion that is the result of large retail shopping centers on both sides of 10th Street.

County Route G7 also serves Frazier Lake Airpark via Frazer Lake Road, as well as the Christopher Ranch garlic facility.

Almaden Expressway at its interchange with Route 85

County Route G8 is an important north–south arterial road from the south valley area of Santa Clara County, California, USA to near Downtown San Jose. G8 runs for 29.4 miles (47.3 km) over both rural roads, expressway and urban streets, but it is most commonly known by residents for its expressway portion, Almaden Expressway. G8 is also part of the Santa Clara County expressway system.

Route description

G8 begins in the south at its junction with State Route 152 in Gilroy. It proceeds north along Watsonville Road as a two-lane country road until it reaches the intersection of Watsonville Rd and Uvas Road. G8 turns left and proceeds north along Uvas Road which is a winding two-lane mountain road that passes by Uvas, Chesbro and Calero reservoirs and their surrounding parks. In Calero Reservoir County Park, Uvas Road is renamed McKean Road and proceeds into the Almaden Valley area of San Jose. At the north end of McKean Rd, G8 turns briefly right on Harry Road for a short distance and then left on to the south end of Almaden Expressway.

As Almaden Expressway, G8 begins as a 2-lane undivided road for 1/2 mile before expanding to 4-lane divided expressway approaching the intersection of Almaden Road. Almaden Expressway eventually expands to a 6-8 lane expressway with the majority of access limited to major intersections controlled by traffic signals. The major exception to this is near Highway 85 and Blossom Hill Road (G10) where there are several major shopping centers.

G8 intersects G10 at Blossom Hill Rd and SR 85 a quarter mile north. This interchange is one of the busiest in Silicon Valley due to several shopping centers and a Costco warehouse store all sharing driveways with this interchange. G8 continues north resuming its expressway design. G8 shares a separated grade interchange with the terminus of Capitol Expressway Auto Mall and again with Murillo Avenue and Tully Road and Curtner Avenue. Other intersections along this part of the route are at grade. Almaden Expressway crosses State Route 87 with which it shares a northbound only interchange.

G8 continues past the north end of Almaden Expressway on to Almaden Road as a 4-lane city street. At the intersection Almaden Road and Alma Avenue, G8 turns east along Alma Ave and proceeds for about a quarter mile to its eastern terminus at First Street (former SR 82).


G8 was originally designated in 1962 along Almaden Expressway which had begun construction in 1959. Almaden Expressway was not completed to its southern terminus until 1984. Before that time the section between McKean Rd and the southern end of the expressway (which was further north at the time) took a zig zag path from McKean Rd to Harry Rd to Almaden Road (S) to Barnes Lane, to the then southern end of Almaden Expressway.

G8 is signed sporadically along its entire length.

County Route G10 (CR G10), known as Los Gatos-Saratoga Road, Los Gatos Boulevard, and more commonly known along the majority of its route as Blossom Hill Road for the majority of its length, is an important east–west arterial roadway through the Almaden Valley area of Santa Clara County, California, United States in the Silicon Valley. The route runs for 10.34 miles (16.64 km) and is a series of city streets for its entire length.

Route description

County Route G10 begins at its western end at the junction of SR 17 and Los Gatos-Saratoga Road (formerly Saratoga Avenue) in Los Gatos. It travels east on Los Gatos-Saratoga Road to the end of that road then turns northeast along Los Gatos Boulevard. CR G10 proceeds for about 34 mile (1.2 km) to Blossom Hill Road where it turns east. Along this stretch, CR G10 is a narrow road that proceeds over Blossom Hill, the hill that the road takes its name from. At the base of Blossom Hill, CR G10 enters San Jose and the Almaden Valley neighborhood.

CR G10 proceeds as a busy 4-6 lane artery through this area, intersecting Almaden Expressway and further east, through the Blossom Valley neighborhood of San Jose, to SR 85. Prior to the completion of the segments of SR 85 between 1991 and 1994, which CR G10 roughly parallels, Blossom Hill Road was the major accessway to this area of San Jose from the west.

CR G10 reaches its eastern terminus at former prior-to-2013 SR 82, a few hundred feet (~100 meters) shy of US 101. Blossom Hill Road continues to US 101 and then over the freeway becoming Silver Creek Valley Road, before continuing as Nieman Boulevard and terminating at the junction with Capitol Expressway.


G10 was designated in 1964 as a county road. As of 2005, however, the road is no longer maintained by the county and is city street along its entire length. G10 is also only sporadically signed along its route and has been largely abandoned by the county after the completion of SR 85.

Where Capitol Expressway turns west toward I-680 in Alum Rock, Capitol Avenue continues north, ending in Milpitas at an intersection with Montague Expressway.


Capitol Expressway was designated in 1978 from Almaden Expressway to US 101, including what is now Capitol Expressway Auto Mall. Construction on the eastern portion from US 101 to I-680 was not completed until 1997.

In the late 1990s the portion of the expressway from Almaden Expressway to SR 87 was transferred from Santa Clara County to the city of San Jose, as part of an auto dealer assessment district improvement plan.[16] San Jose converted it into an auto row and renamed it Capitol Expressway Auto Mall.
