San Francisco, a picturesque city known for its iconic skyline and diverse culture, is also home to some of the world’s most famous bridges. These architectural marvels not only serve as vital transportation links but also as symbols of the city’s rich history and engineering prowess. So, how many bridges does San Francisco have? Let’s find out.

There are two main bridges that are most commonly associated with San Francisco:

The Golden Gate Bridge

Opened in 1937, this iconic suspension bridge spans the Golden Gate Strait, the entrance to the San Francisco Bay from the Pacific Ocean. With a total length of 8,981 feet (2,737 meters) and a main span of 4,200 feet (1,280 meters), it held the title of the world’s longest suspension bridge until 1964. The bridge is painted in the famous “International Orange” color, which not only makes it visually striking but also enhances its visibility in the city’s frequently foggy weather.

The San Francisco-Oakland Bay Bridge

Also known as the Bay Bridge, this complex structure consists of two separate spans that connect San Francisco to Oakland and the rest of the East Bay. The western span, which opened in 1936, is a double suspension bridge, while the eastern span, completed in 2013, is a self-anchored suspension bridge. The Bay Bridge is a critical transportation artery, carrying over 260,000 vehicles per day as you can see from B On The Run travel blog.

In addition to the two main bridges, there are several smaller bridges within the city limits and its vicinity:

The Al Zampa Memorial Bridge

Also known as the Carquinez Bridge, this suspension bridge spans the Carquinez Strait and connects the cities of Crockett and Vallejo. It is part of Interstate 80 and opened in 2003.

The Dumbarton Bridge

This bridge connects Menlo Park in the San Francisco Peninsula with Newark in the East Bay. It is a steel girder bridge that was opened in 1982 and carries State Route 84.

The Richmond-San Rafael Bridge

This bridge connects the city of Richmond in the East Bay with San Rafael in the North Bay. It is a cantilever bridge that opened in 1956 and carries Interstate 580.

The San Mateo-Hayward Bridge

This bridge connects San Mateo on the San Francisco Peninsula with Hayward in the East Bay. It is a combination of a high-level bridge and a causeway that opened in 1967 and carries State Route 92.

The Benicia-Martinez Bridge

This bridge connects the city of Benicia in the North Bay with Martinez in the East Bay. It is a combination of a truss bridge and a cable-stayed bridge that opened in 2007 and carries Interstate 680.


In conclusion, San Francisco is home to two main bridges, the Golden Gate Bridge and the San Francisco-Oakland Bay Bridge, as well as several smaller bridges in the surrounding areas. These engineering marvels play a crucial role in connecting the city with its neighboring communities and enhancing the region’s transportation infrastructure.
