Presidio Parkway

Genres: Nonfiction
The Presidio Parkway is the new south access to the iconic Golden Gate Bridge, which connects San Francisco to the North Bay counties. It replaced the original access structure, known as Doyle Drive, which was built together with the bridge in 1936. Doyle Drive was originally designed as a series of viaducts to fly over what was then a military base, the Presidio of San Francisco. Built to the standards of the 1930s, with six narrow lanes, no shoulders, and no dividing barrier between the two directions of travel, the facility could not handle even minor traffic incidents without creating major backups on the bridge.

Why Replace Doyle Drive?

Guest 2 months ago

The historic south access road to the iconic Golden Gate Bridge, known as Doyle Drive or Route 101, was structurally and seismically deficient at the start of construction in 2009. The roadway was facing the same problem that threatens other parts of our nation's infrastructure - the ravages of time and continual use. Originally built in 1936, Doyle Drive had reached the end of its useful life. In April of 2012, traffic was shifted onto a seismically-safe temporary bypass that carried traffic until the final roadway was opened on July 12, 2015. Construction activity is continuing through 2017 and includes removing the temporary bypass, reconstructing Halleck Street, covering the tunnels and installing landscaping.
