Construction of the Presidio Parkway was planned in two major phases in order to:
- Receive federal stimulus funding and begin construction sooner;
- Achieve seismic safety faster by switching traffic off of Doyle Drive and onto the completed Phase I structures (completed in April 2012);
- And shorten the total length of construction from the original schedule.
Phase I: Design-Bid-Build
Phase I of construction was completed in April 2012, and consisted of a replacement bridge on Highway 1 north of the MacArthur Tunnel and the new southbound Presidio Viaduct, constructed by C.C. Myers. It also included the first of four short tunnels, the southbound Battery Tunnel, and a temporary bypass constructed by R&L Brosamer. Seismic safety on Doyle Drive was achieved when traffic was shifted onto a temporary bypass in April 2012.
This phase was delivered through the traditional design-bid-build financial model typically used in California.
Phase II: Public-Private Partnership
Phase II pre-construction began in mid-2011. Major construction will begin in late 2012 and construction will continue through 2015 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. This phase will also include final landscaping.
Phase II will be delivered through a public-private partnership (P3). This will be the first project in California to operate under this financial model. The selected bidder (Golden Link Partners) will design, build, finance, operate and maintain the project for 30 years. The P3 method of delivery will reduce costs, free up state funding for other uses, transfer cost-overrun risks to the private developer, and ensure a high maintenance standard during the 30 year contract.
