What is park street bridge alameda?

The Park Street Bridge is a double-leaf bascule bridge that spans the Oakland Estuary in Alameda, California. The bridge was built in 1936 to replace an older drawbridge and is named after Park Street, the main thoroughfare that it connects in Alameda. It was designed by the California Department of Public Works and is made of steel and concrete.

The bridge is 3,423 feet in length and has a clearance of 30 feet when closed and 169 feet when open. It carries approximately 22,700 vehicles across the estuary each day and is a key transportation link between the cities of Alameda and Oakland.

In recent years, the bridge has undergone several renovations to modernize its mechanical, electrical, and hydraulic systems and extend its lifespan. These upgrades have allowed the bridge to continue serving as a vital transportation link for residents and tourists alike.
