The following is a list of state highways in Maryland shorter than one mile (1.6 km) in length with route numbers between 2 and 699. Most of these highways act as service roads, old alignments of more prominent highways, or connectors between one or more highways. Many of these highways are unsigned and have multiple segments with the same number. Several of these highways have their own articles; those highways are summarized here and a link is provided to the main article. This list does not include highways where at least one highway of that number is at least one mile in length. All highways at least one mile in length have their own article. The highways shorter than one mile with the same number are covered in the main article for the highway.
View north from the south end of MD 79 at MD 17 and MD 464 in Rosemont
Maryland Route 79 is the designation for the state-maintained portion of Petersville Road, which runs 0.85 miles (1.37 km) from MD 17 and MD 464 in Rosemont north to a bridge over the Little Catoctin Creek on the northern border of Rosemont. MD 79 begins at a four-way intersection on the boundary between the town of Brunswick to the south and the village of Rosemont to the north. Petersville Road continues south as MD 17 into Brunswick; MD 17 also heads west along Burkittsville Road. The eastern leg of the intersection is MD 464 (Souder Road). MD 79 heads northeast as a two-lane undivided road through a residential area where the highway meets the eastern end of Rosemont Drive, which is unsignedMD 871G. The state highway comes to its northern terminus at a bridge over Little Catoctin Creek on the northern border of Rosemont. Past the northern terminus, Petersville Road continues north as a county road toward MD 180 (Jefferson Pike) in Petersville.[1][2]
Petersville Road was constructed as a 14-foot (4.3 m) wide macadam-surfaced highway from Jefferson Pike (designated US 340 and later MD 180) south to Brunswick in 1916.[3] When state highways were first numbered in Maryland in 1927, the portion of Petersville Road south of what is now Rosemont Drive became MD 33; MD 33 became MD 17 in 1940.[4][5] Petersville Road from Rosemont north to Petersville was later marked as MD 79.[6] MD 79's modern bridge over Little Catoctin Creek was built in 1941 after the previous bridge was carried away by a flood that year.[7] MD 79 was extended south to its current southern terminus in 1968 when MD 17 was relocated to its present course through Rosemont and MD 464 was extended west along Souder Road to its present terminus to form the fourth leg of that intersection.[8] On October 31, 2016, the northern terminus of MD 79 was cut back from MD 180 to its current location when the section of Petersville Road between the Little Catoctin Creek bridge on the northern border of Rosemont and MD 180 was transferred to county maintenance.[9]
Maryland Route 169 is the designation for Maple Road, a 0.97-mile (1.56 km) state highway in Linthicum in northwestern Anne Arundel County.[1] The highway begins at Hammonds Ferry Road and heads east as a two-lane undivided road through a residential area. MD 169 has a grade crossing of MTA Maryland's Baltimore Light RailLink just prior to its intersection with MD 170 (Camp Meade Road). The highway reaches its eastern terminus at MD 648 (Baltimore–Annapolis Boulevard).[10]
View north from the south end of MD 172 in Orchard Beach
Maryland Route 172 is the unsigned designation for Arundel Cove Avenue, a 0.17 mi (0.27 km) route that runs from railroad tracks in Orchard Beach in Anne Arundel County north to MD 173 (Hawkins Point Road) in the city of Baltimore.[1][11] This state highway once served as the entrance to the United States Coast Guard Yard. The yard is now accessed from MD 173 just to the west of MD 172.[12] MD 172 was constructed by 1930.[13]
Maryland Route 181 is the unsigned designation for the Sixth Street drawbridge over the Spa Creek in Annapolis, Anne Arundel County. The route was designated in 2009 and is 0.16 mi (0.26 km) long.[1]
Maryland Route 219 is the designation for Ninth Street, a two-lane undivided road which runs 0.22 miles (0.35 km) from the intersection of US 219 and MD 135 north to High Street within Oakland in Garrett County. MD 219 is state-maintained from US 219 to Green Street and maintained by the town of Oakland from there to High Street.[1][14] The state highway follows the southernmost part of the alignment of the future Oakland Bypass.
MD 250A approaching US 13 and US 113 in Pocomoke City
Maryland Route 250A is the unsigned designation for Old Virginia Road, which runs 0.19 mi (0.31 km) from US 13 Business east to the intersection of US 13 and US 113 within Pocomoke City in Worcester County.[1][16] The state highway is the southernmost part of the second alignment of US 113 in Pocomoke City. MD 250A was assigned shortly after US 113 was rolled back to terminate at the Pocomoke City Bypass, US 13, in the 1960s.
View north at the south end of MD 268 at Main Street in Elkton
Maryland Route 268, which is known as North Street, runs 0.95 miles (1.53 km) from Main Street north to MD 279 within the town of Elkton in eastern Cecil County. The highway begins at Main Street, which is one-way eastbound, in downtown Elkton; the parallel street that allows westbound traffic and provides access to Union Hospital and MD 213 (Bridge Street) is High Street one block to the north. MD 268 heads north as a two-lane undivided road and passes a block to the east of the Elkton Armory. The highway veers slightly to the west to cross over Amtrak's Northeast Corridor railroad line. The old alignment, Old North Road, consists of pair of stubs on the south and north sides of the tracks with unsigned designations MD 727 and MD 727A, respectively. MD 268 continues north between Big Elk Creek to the east and Elkton Middle School to the west before reaching its northern terminus at MD 279, which heads west as Newark Avenue and east as Elkton Road toward Newark, Delaware.[MD 268 1][MD 268 2]
MD 268 is the old alignment of MD 279 within Elkton.[MD 268 3] North Street was paved as a 15-foot-wide (4.6 m) concrete road by 1921.[MD 268 4][MD 268 5] The original North Street overpass of the Pennsylvania Railroad (now Amtrak) was constructed between 1930 and 1934.[MD 268 6][MD 268 7] The bypassed street stubs to the closed grade crossing were designated MD 727 and MD 727A in 1949.[MD 268 5] MD 268 was assigned to North Avenue after MD 279 was extended west to US 40 to bypass the center of Elkton in 1968.[MD 268 8][MD 268 9] The highway's current bridge across the Amtrak Northeast Corridor was constructed between 1986 and 1988.[MD 268 10]

View south along MD 284 at MD 285 in Chesapeake City
Maryland Route 284 is the designation for Hemphill Street, which runs 0.25 miles (0.40 km) between two intersections with MD 285 in Chesapeake City in southern Cecil County. MD 284 heads north from MD 285 (Biddle Street) one block north of the Chesapeake & Delaware Canal in the town of Chesapeake City. Immediately after leaving the town limits, the two-lane undivided highway curves to the west and reaches its northern terminus at MD 285 (Lock Street). MD 285 heads north to a junction with MD 213 (Augustine Herman Highway).[MD 284 1][MD 284 2]
Hemphill Street was part of the original Cecilton–Elkton highway passing through Chesapeake City that was designated for improvement by the Maryland State Roads Commission in 1909.[MD 284 3] The highway through Chesapeake City was paved as a 14-foot-wide (4.3 m) concrete road in 1915.[MD 284 4] At that time, the main highway entered Chesapeake City from the north along Hemphill Street, crossed the Chesapeake & Delaware Canal on a one-lane bridge, turned west and crossed Back Creek on a wooden bridge, turned south onto Bohemia Street in South Chesapeake City, turned west onto Third Street, and turned south onto George Street to leave the town.[MD 284 5]
In the 1920s, the U.S. Army Corps of Engineers widened, straightened, and deepened the canal. As part of their work, the agency constructed a vertical lift bridge across the canal.[MD 284 6] Between 1924 and 1926, the Maryland State Roads Commission constructed approaches to the new bridge on both sides of the expanded canal, eliminating two narrow and dangerous bridges and four right-angle turns in Chesapeake City.[MD 284 7] The new route along George Street and Lock Street, which became part of US 213 in 1927 and is now MD 285 and MD 537, entirely bypassed what is now MD 284.[MD 284 8][MD 284 1][MD 284 9] MD 284 was resurfaced with bituminous concrete in 1976, and its junction with MD 285 was changed from a tangent to the present orthogonal intersection in 1982.[MD 284 10]

View north along MD 308 at MD 313/MD 318 in Federalsburg
Maryland Route 308 is the designation for a portion of South Main Street in Federalsburg, Caroline County running from MD 313/MD 318 north to the end of state maintenance, where South Main Street continues north as a municipal street. The route is 0.12 miles (0.19 km) long. Although not signposted, it does appear in official documents and some commercial maps.[1]
Maryland Route 324 is the unsigned designation for Maple Avenue, which runs for 0.40 mi (0.64 km) from MD 16/MD 331 south to the southern town limit of Preston in Caroline County, where the highway continues as county-maintained Choptank Road.[1][17]
View west along MD 327 at Marion Tapp Parkway in Perryville
Maryland Route 327, which is known as Ikea Way, runs 0.51 miles (0.82 km) from MD 7 east to a dead end within the town of Perryville in southwestern Cecil County. MD 327 begins at an intersection with MD 7 (Broad Street) on the eastern edge of the town of Perryville. The state highway heads southeast as a two-lane undivided road and crosses over Amtrak's Northeast Corridor railroad line. MD 327 comes to an intersection with Marion Tapp Parkway, which leads southwest to the entrance of the adjacent Perryville Wastewater Treatment Plant and to Perryville Community Park located at the Perry Point promontory east of the Perry Point VA Medical Center property.[MD 327 1][MD 327 2] From here, the route passes south of an IKEAdistribution center before it reaches a dead end.[MD 327 1][MD 327 3]
In a March 8, 1967, agreement, the Maryland State Roads Commission agreed to transfer maintenance of part of MD 7 and all of MD 271 to the town of Perryville upon the completion of a new highway and bridge from MD 7 across the Pennsylvania Railroad (now Amtrak) to serve the peninsula south of the railroad between Mill Creek and Furnace Bay.[MD 327 4] The new highway, designated MD 327, was constructed in 1968, the same year Firestone Plastics opened a chemical plant on the present site of the IKEA distribution center.[MD 327 3][MD 327 5] The state highway had no name as of 1999; it was designated Firestone Road in 2001 and Ikea Way in 2004 shortly after the opening of the IKEA distribution center.[MD 327 3][MD 327 6][MD 327 7][MD 327 8] In 2018, MD 327 was extended east from Marion Tapp Parkway to a dead end after it was determined that stretch of Ikea Way was maintained by the state.[MD 327 1]

Maryland Route 334 is a state highway in Talbot County that runs along two-lane undivided Port Street from MD 322 on the western edge of the town of Easton, eastward to Washington Street. MD 334 starts in the west at the intersection with MD 322 (Easton Parkway), where Port Street continues west as a county road toward a dead end along the Tred Avon River. It passes through a somewhat rural side of the town, changing quickly to a residential corridor. East of the Clay Street intersection, the road becomes municipally maintained. The route comes to its eastern terminus at Washington Street.[1]
Sign for MD 368 along eastbound MD 367 in Bishopville
Maryland Route 368 is the designation for St. Martins Neck Road, a 0.28 mi (0.45 km) spur that runs from the beginning of state maintenance north to MD 367 in Bishopville.[1] St. Martins Neck Road continues southeast as a county highway to Isle of Wight, where it has an at-grade intersection with MD 90 (Ocean City Expressway).[18] MD 368 originally also included present day MD 568 and MD 367 between the two roads; MD 368 was shortened to its present length in 1950.[6][19]
Maryland Route 375 is the unsigned designation for Commerce Street, a 0.06 mi (0.097 km) street that runs one-way west (officially north) from MD 818 (Main Street) to MD 374 (Broad Street) within downtown Berlin.[1][20]
Maryland Route 377 is the designation for Williams Street, which runs 0.78 mi (1.26 km) from MD 376 in the Berlin Commercial District north to MD 346 (Old Ocean City Boulevard) just west of US 113 within Berlin.[1][21]
Maryland Route 430 is the unsigned designation for Greenbelt Road, which runs 0.49 mi (0.79 km) from US 1 east to MD 193 within College Park. MD 430 serves to complete movements missing from the US 1-MD 193 interchange to the north of MD 430's western terminus.[1][23] The entire length of MD 430 is part of the National Highway System.[22]
Maryland Route 432 is the unsigned designation for Glen Oaks Lane, which runs 0.25 mi (0.40 km) from the intersection of Guilford Road and Oakland Mills Road east to a cul-de-sac adjacent to I-95's interchange with MD 32 (Exit 38) in Columbia.[1][24]
This section is about the current Maryland Route 449. For the former highway, see Maryland Route 449 (former).
MD 449 at MD 213 in Locust Grove
Maryland Route 449 is the unsigned designation for the 0.07-mile-long (0.11 km) section of Shallcross Wharf Road from MD 213 east to MD 444 near Locust Grove in northern Kent County.[MD 449 1][MD 449 2] The course of MD 449 and Shallcross Wharf Road northeast to Old Locust Grove Road were part of the original Chestertown–Galena highway proposed for improvement as a state road in 1909.[MD 449 3] This stretch was constructed as a 14-foot-wide (4.3 m) macadam road in 1912.[MD 449 4] After US 213's bypass of Locust Grove was built in 1950 and 1951, the old path of US 213 through Locust Grove—Shallcross Wharf Road between the western end of the bypass and the center of Locust Grove, and Old Locust Grove Road between the center of Locust Grove and the eastern end of the bypass—became part of MD 444, with what is now MD 449 being a spur of the main route.[MD 449 5][MD 449 6] After MD 444's present course west of Locust Grove was constructed in 1968, Old Locust Grove Road became MD 447, and the 0.32-mile-long (0.51 km) portion of Shallcross Wharf Road between US 213 and the new MD 447 became MD 449.[MD 449 5][MD 449 7] MD 449 was resurfaced with bituminous concrete in 1984.[MD 449 8] Three years later, MD 449 was transferred from state to county maintenance through a December 1, 1987, road transfer agreement.[MD 449 9] However, the portion of MD 449 between MD 213 and MD 444 was returned to state control to be destroyed, but the highway remained in use. Thus, in 1997, MD 449 was returned to the inventory of the state highway system.[MD 449 10]

Maryland Route 460, which is known as Hall Highway, runs 0.78 miles (1.26 km) from McCready Memorial Hospital east to MD 413 within Crisfield in southwestern Somerset County. The highway begins just north of the McCready Memorial Hospital property on a peninsula between Daugherty Creek and the Little Annemessex River. The roadway continues north as county-maintained Byrd Road. MD 460 heads south, entering the city limits of Crisfield and passing through the hospital grounds, where the highway is flanked by perpendicular parking spaces. The state highway turns east and crosses the Little Annemessex River, then passes through a residential neighborhood where the highway intersects Wynfall Avenue, which provides full access to MD 413. MD 460 reaches its eastern terminus at southbound MD 413 (Maryland Avenue). There is no direct access to northbound MD 413 (Richardson Avenue).[1][25] McCready Memorial Hospital was founded in 1923 as a memorial to Edward W. McCready, a cork industry scion and Crisfield native who was killed in a train–automobile collision on the Crisfield–Westover road in 1919.[26] MD 460 was constructed around 1933 to provide a more direct connection between the hospital and the populated areas of Crisfield.[27]

Maryland Route 537 is a collection of unsigned state highways in the U.S. state of Maryland. These two existing highways and two former sections of state highway are segments of old alignment of U.S. Route 213 (US 213), which is now MD 213, in Chesapeake City in southern Cecil County.[MD 537 1][MD 537 2] Some of the roads that became segments of MD 537 were constructed in the mid-1910s as part of the original state road between Elkton and Cecilton.[MD 537 3] Other portions of MD 537 were part of the approach roads to a bridge across the Chesapeake & Delaware Canal that was built in the mid-1920s and destroyed in 1942.[MD 537 4][MD 537 5] After the modern Chesapeake City Bridge and its approach roads were completed in 1949, US 213 was moved to the new bridge and approach roads and MD 537 was assigned to the bypassed sections of US 213.[MD 537 2][MD 537 5] Much of MD 537 outside of Chesapeake City was transferred to county maintenance in the late 1950s.[MD 537 2] In 2015, the remaining section of MD 537 north of the canal was turned over to municipal maintenance.[MD 537 6]
