Presidio Parkway
The Presidio Parkway is the new south access to the iconic Golden Gate Bridge, which connects San Francisco to the North Bay counties.

Why Replace Doyle Drive?
Guest 4 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.Write Review:
