Presidio Parkway

The Presidio Parkway is a roadway tucked into the natural contours of the Presidio of San Francisco and the Golden Gate National Recreation Area, one of the nation’s largest urban parks. Presidio Parkway will create a regional gateway between the Golden Gate Bridge and the city of San Francisco and North Bay communities.


WSP USA, formerly WSP | Parsons Brinckerhoff, was the prime consultant for the environmental impact statement/report, in joint venture: provided general engineering, final design and construction support services; P3 contract services. The project team strived to create a roadway that reduced impacts to biological, cultural and natural resources; respected the project setting within a national park, the National Historic Landmark District, and the surrounding neighborhoods; met community needs; and provided a safer roadway.

Now complete, the Presidio Parkway has three travel lanes in each direction—two 11-foot (3.3-meter) lanes and one 12-foot (3.6-meter) lane to accommodate buses—separated by a landscaped median ranging from 16 to 41 feet (5 to 12.5 meters). Wider lanes, the new median and continuous shoulders will improve safety. Pedestrians and bicyclists will also benefit from numerous new opportunities to cross over or under the parkway to access the shoreline. 

Other project elements include new steel and concrete bridges, two cut-and-cover tunnels and an at-grade roadway with landscaped berms—all designed to withstand a high magnitude 8 earthquake without danger of collapse and/or easily repairable damage. The first phase of this project was completed under a design-bid-build procurement and the second phase will be constructed under a P3 procurement (design-build-finance-operate-maintain), with the private concessionaire providing operations and maintenance services on the new roadway for 30 years.

The Presidio Parkway opened to traffic in July 2015. Read a feature article and see additional photos here.
