Presidio Parkway

San Francisco, California

Kiewit was a member of the design-build joint venture (35%) that completed the reconstruction of Doyle Drive, also known as the Presidio Parkway. Caltrans elected to proceed with this complex project under a Public Private Partnership (P3) delivery method. The project upgraded the southern approach to the Golden Gate Bridge by providing a new six-lane parkway-type roadway and a southbound auxiliary lane, between the Park Presidio Interchange and the new Presidio access at Girard Road. The scope of work included placing the freeway partially below ground through cut and cover tunnels, replacing the outdated roadway and bridge structures, and providing an overall improvement to the historical Presidio property.

During construction, Kiewit worked with Caltrans and the Presidio Trust to make certain the public and people that live and work on the Presidio have access to information that is accurate and timely. One of the primary goals of the project is to improve mobility and safety for the traveling public. Doyle Drive and the Golden Gate Bridge are a primary evacuation route in the event of an earthquake in San Francisco. Therefore it was critical to make certain that all of the structures were robust enough to withstand a major seismic event.
