Originally built in 1936 as one of the New Deal projects, Doyle Drive had reached the end of its useful life after over 75 years of use. The existing south access road to the Golden Gate Bridge, Doyle Drive or Route 101, was structurally and seismically deficient and needed to be replaced.
Since the early 1970's, the California Department of Transportation (Caltrans) has been preparing plans for updating Doyle Drive’s aging infrastructure. Various Caltrans studies were undertaken and in 1992, the Board of Supervisors established a Doyle Drive Task Force to consider Caltrans’ design concepts and determine a preferred replacement alternative. In February 1993, the Task Force submitted its recommendations to the Board of Supervisors. Caltrans then completed a Project Study Report (PSR) in that same year, which contained several alternatives for the replacement of Doyle Drive and took into consideration the recommendations of the Doyle Drive Task Force. This report was the first step toward securing state funding for the project.
In 1996, the San Francisco Transportation Authority (SFCTA) completed the Doyle Drive Intermodal Study, which called for the following features to be included in the replacement project to support multimodal transit:
- A center divider barrier to eliminate head-on collisions
- Direct vehicular and transit access to the new Presidio National Park
- Vastly improved design to expand views of the Golden Gate Bridge and the National Park and increase safety
- Expanded transit, car pooling and alternative commute options
- Intelligent Transportation System (ITS) technologies for vehicular safety enhancement and transit schedule coordination.
Environmental assessment for the project began in 2000, and the Draft Environmental Impact Statement/Report (DEIS/R) was released in 2005. On September 26, 2006, the Transportation Authority's Board of Commissioners unanimously selected the Presidio Parkway alternative, a design created by local landscape architect Michael Painter. .
Input received during the comment period, as well as refinements to the Preferred Alternative, are reflected in the Final Environmental Impact Statement/Report (FEIS/R) that was circulated in October 2008 and certified on December 16, 2008. To ensure that the project reflected community needs, a comprehensive public involvement and agency coordination program was conducted. Community consensus on the project’s design was achieved in 2009.
The Doyle Drive replacement project is jointly led by the SFCTA and Caltrans. In addition to funding provided from SFCTA's Prop K transportation sales tax and the State of California, the Metropolitan Transportation Commission and the Golden Gate Bridge Highway and Transportation District have committed regional funding to the project.
