→State Route 75 (SR 75) is a short, 13-mile (21 km) expressway in the U.S. state of California. It is a loop route of Interstate 5 in the Barrio Logan Community in San Diego and the route ends at Interstate 5 in South San Diego near San Ysidro. It includes the San Diego-Coronado Bay Bridge, a bridge that traverses the San Diego Bay and directly passes through Coronado with the mainland, continuing down along the Silver Strand, a thin strip of land, before joining back with Interstate 5 in South San Diego.

[edit] Route description
This route is eligible for the State Scenic Highway System.[2] It is signed as a scenic route for nearly its entire length, from the Imperial Beach city limit to Avenida del Sol in Coronado.[3]
SR 75 begins as Palm Avenue at I-5, heading westbound from the Southland Plaza mall. The route travels west between the communities of Palm City and Nestor before entering the city limits of Imperial Beach. In Imperial Beach, SR 75 curves to the north, becoming Silver Strand Boulevard and crossing into Coronado and continuing onto the peninsula containing Coronado Island, separated from the mainland by San Diego Bay. The highway continues through the Silver Strand Training Complex and the South Bay Study Area before entering the Coronado Cays subdivision and paralleling Silver Strand State Beach.[4]
After this, SR 75 passes through the United States Naval Amphibious Base for a few miles before entering downtown Coronado. The highway becomes Orange Avenue and turns north-northeast as the main street through Coronado. SR 75 intersects SR 282 at the one-way couplet of Third and Fourth Streets; SR 282 continues west on Third Street and returns to SR 75 on Fourth Street, while SR 75 continues east on Fourth Street and heads west towards Orange Avenue on Third Street. The one-way couplet is brief, and SR 75 briefly becomes a divided highway before crossing the Coronado Bridge. While on the bridge, SR 75 crosses into the city of San Diego again.[4]
Once on the mainland, SR 75 has a northbound exit to National Avenue and a southbound entrance from Cesar E Chavez Parkway. Through traffic is directed onto I-5 south or north in Logan Heights, and SR 75 ends.[4]
[edit] History
The route was originally established in 1963 with two segments.[5] Coronado Bridge was added to the route in 1967, and in 1976 a southern section was deleted and renumbered SR 905.
