Presidio Parkway is the first public-private partnership transportation project delivered in the state under the recently enacted P3 statute and a Greenroads project. The project is a collaborative effort by the California Department of Transportation, the San Francisco County Transportation Authority, and the Federal Highway Administration, who reached financial close with developer Golden Link Concessionaire, LLP on Phase II of the project on June 14, 2012.

Presidio Parkway replaces Doyle Drive, the aging approach to the Golden Gate Bridge used by more than 120,000 vehicles each day. Originally built in 1936, the roadway is structurally and seismically deficient. The Presidio Parkway project improves seismic, structural and traffic safety, as well as integrates the roadway into the national park setting and creates additional recreation space.

Major construction began in 2012 through 2015. Construction includes the northbound Presidio Viaduct and Battery Tunnel, the Main Post Tunnels and the new Girard Road Interchange with a direct connection to the Presidio. This phase also includes final landscaping.

HOCHTIEF and Meridiam are the project’s developers and equity partners. HTNB Corporation is the lead engineering firm on the project. The P3 method of delivery will reduce costs for the owner and ensure a high maintenance standard during the more than three-decade long contract.
