High Quality Content by WIKIPEDIA articles! State Route 275 (SR 275) is a short unsigned state highway in the Sacramento area of the U.S. state of California. The highway, also known as Tower Bridge Gateway (formerly West Sacramento Freeway), is a short spur from Interstate 80 Business in West Sacramento over the Tower Bridge into downtown Sacramento. Despite its deletion from the Streets and Highways Code in 1996, the California Department of Transportation (Caltrans) still maintains about half of the route; approximately 1/2 mile (1 km) was relinquished to West Sacramento in 2001 and about the same (along Capitol Mall) to Sacramento in 2006. (Similarly, State Route 160 is still a state highway north of the American River in Sacramento, but the legislative description ends at the south city limits.) West Sacramento is in a continuing project to replace the freeway with a pedestrian-friendly street.
