Presidio Parkway

The Presidio Parkway project is a replacement of Doyle Drive, a 1.6-mile segment of Route 101 in San Francisco that is the southern access to the Golden Gate Bridge, connecting Marin and San Francisco counties and providing a major regional traffic link between the peninsula and North Bay Area counties. The current structure, built in 1936, does not meet current highway standards and is seismically deficient.

The Presidio Parkway project area extends from the Golden Gate Bridge Toll Plaza on the west to Broderick Street on the east, and includes Richardson Avenue, Gorgas Avenue and Marina Boulevard. The Presidio Parkway will be a six-lane facility with a southbound auxiliary lane between the Park Presidio Interchange and the new Presidio access at Girard Road. The roadway will consist of various sections (from the toll plaza east to Richardson Avenue) with a landscaped median:

• a high-viaduct between the Park Presidio Interchange and the San Francisco National Cemetery (Presidio Viaduct)
• shallow cut-and-cover tunnels past the cemetery to Battery Blaney (Battery Tunnels)
• at-grade roadways to the Main Post
• cut-and-cover tunnels from the Main Post to east of Halleck Street (Main Post Tunnels)
• a low causeway from Halleck Street to Girard Road
• at-grade connection to Richardson Avenue

The project is being developed in two phases. Caltrans is responsible for the design, financing and construction of Phase I, currently nearing completion. Phase I, delivered through a traditional design-bid-build process, consists of a replacement bridge at the Park Presidio Interchange, the new southbound Presidio Viaduct, the southbound Battery Tunnel, and a temporary bypass east of the Main Post to allow construction of the Main Post Tunnels and roadway to Richardson Avenue.

Through a competitive procurement process, Caltrans selected a private consortium, the Golden Link Concessionaire, to deliver Phase II as a design, build, finance, operate, and maintain (DBFOM) availability-pay concession. The P3 Project Agreement with GLC was executed on January 3, 2011. GLC will receive milestone payments following substantial completion and quarterly availability payments through the concession period, based on performance.

Phase I construction was substantially completed and opened to the public on April 30, 2012. Because Phase I consists of six contracts to complete the remaining elements of the Presidio Parkway, including the northbound Presidio Viaduct and Battery Tunnel, the Main Post Tunnels, and the new Girard Road interchange with a direct connection to the Presidio, it is expected that the entire Phase I will be completed by late January 2014/early 2015. This phase will also include final landscaping. While several minor construction activities are underway (e.g. site preparation and stormwater prevention, limited demolition and utility relocation), Phase II major construction has not yet begun.
