Watch falsework being lowered on the new Presidio Parkway project.
Presidio Parkway will replace 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 will improve seismic, structural and traffic safety, as well as integrate the roadway into the national park setting and create additional recreation space.
Flatiron is the design-build lead for Golden Link Concessionaire, LLP who will design, build, finance, operate and maintain the project for 33.5 years. HOCHTIEF and Meridiam are the project's developers and equity partners. HTNB Corporation is the lead engineering firm on the project. The PPP method of delivery will reduce costs for the owner and ensure a high maintenance standard during the more than three-decade long contract.
Presidio Parkway is the first public-private partnership transportation project delivered in California under the recently enacted PPP statute. 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.
Major construction began in 2012 and will continue 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 will also include final landscaping.
