Arch truss bridge in San Diego, California

The First Avenue Bridge is a historic metal-truss bridge located in San Diego, California. Built in 1931, it is the only metal truss bridge in the city and one of the few arch truss bridges in California. The bridge played a crucial role in the development of the Uptown district, providing residents with a more efficient commute to downtown offices. Recently, the City of San Diego has proposed a seismic retrofit for the bridge, with Heritage Architecture & Planning overseeing the preservation efforts. The First Avenue Bridge stands as a testament to San Diego's early 20th century civil engineering projects and is a significant piece of the city's architectural history.
