At the north end of SR 185 at International Boulevard and 42nd Avenue, the short State Route 77 (SR 77) heads southwest to Interstate 880.
Route description
The north end of SR 185 then lies just northwest of High Street at 42nd Avenue, where the short State Route 77 heads southwest to Interstate 880. SR 77 was originally signed as SR 185 from SR 185's terminus to I-880; since at least August 2008, Caltrans has erected SR 77 shields in place of SR 185 shields as reassurance markers and freeway entrance signage at SR 77's two on-ramps at International Blvd./42nd Avenue and East 12 Street. SR 77 was originally a freeway; however, in 2011, the interchange with I-880 was converted to consist of intersections, as part of the I-880 High Street Seismic Retrofit Project,[3] therefore SR 77 can no longer be considered a freeway.
The 0.35-mile (0.56 km)[4] State Route 77 is part of a proposed 13.8 miles (22.2 km) route, which would run from I-880 northeast past SR 185 to Interstate 580 near High Street. There, it would turn northwest on I-580 toward Park Boulevard, splitting there to head northeast and north to State Route 24 near Lafayette.[5]
Major intersections
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary ().[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Alameda County.
