In 2009, $122 million in federal stimulus funding from the American Recovery and Reinvestment Act allowed construction to begin a year earlier than expected. The project was carefully designed to withstand the maximum credible earthquake for the region, improve traffic safety and improve access to the Presidio and Golden Gate National Recreation Area.
Phase I Construction
Phase I Construction: Construction of the parkway has been divided into two major phases in order to keep traffic moving during the replacement. During Phase I, crews replaced a bridge on Highway 1 north of the MacArthur Tunnel, completed the southbound High Viaduct along Highway 101, and completed the new southbound Battery Tunnel and a temporary bypass. The project achieved seismic safety in April 2012 following a 57-hour weekend closure of Doyle Drive, during which parts of the old roadway were removed and traffic was shifted onto the completed southbound structures and the temporary bypass. Phase I construction was delivered through the traditional design-bid-build financial model typically used in California.
Phase II Construction
Phase II construction began in summer 2012 to complete the remaining elements of Presidio Parkway, including the northbound High Viaduct and Battery Tunnel, the Main Post Tunnels, the realignment of the Highway 1/101 Interchange, and the new Girard Road Interchange, providing direct connection with the Presidio. In order to achieve greater schedule and budget certainty, and to provide the expected level of operations and maintenance service, Phase II is being delivered through the state’s first public-private partnership (P3). The developer, Golden Link Concessionaire, was selected to design, build, finance, operate and maintain the project for 30 years while Caltrans and SFCTA maintain an oversight role. This P3 method of delivery was selected to 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. Phase II, including restoration and landscaping, is expected to be complete in 2016.
CONSTRUCTION UPDATE | AUGUST 2015
The new Doyle Drive is open for vehicular traffic, although construction activity needed to complete the project will continue into late 2016 and will include restoring portions of the east end, covering the tunnels, and reconstructing Halleck Street. After construction is complete, initial landscaping will be installed.
Crews are installing barrier rails and permanent striping and building a retaining wall between the northbound and southbound roadways between the tunnels. Work will soon occur to prepare to cover the Main Post and Battery Tunnels with lightweight fill and restore Halleck Street across the tunnel tops, which is expected this fall.
Crews will work to restore the parking lot behind the Palace of Fine Arts and reconfigure the Gorgas Avenue/Richardson Avenue intersection with relocated traffic signals and a new median island. To reduce potential cut-through traffic as per the approved environmental document, vehicle access from Gorgas Avenue to Lyon Street will be eliminated, and the connection to Lyon Street will become a pedestrian and bicycle corridor.
