BACKGROUND

The existing south access road to the Golden Gate Bridge, known as Doyle Drive or Route 101, is structurally and seismically deficient and must be replaced. The roadway is facing the same problem that threatens other parts of our nation's infrastructure—the ravages of time and continual use. Originally built in 1936, Doyle Drive has reached the end of its useful life.

Since the early 1970's, Caltrans has been preparing plans for improving Doyle Drive. Various Caltrans studies were undertaken, leading to a 1991 request for acceptance of one or more concepts from the San Francisco Board of Supervisors.

In 1992, the Board of Supervisors established a Doyle Drive Task Force to consider the Caltrans alternatives and determine a preferred replacement alternative. In February 1993 the Task Force submitted its recommendations to the Board of Supervisors. Despite the complexity of the issues, the Task Force achieved an extraordinarily high degree of consensus among all stakeholders, a major step toward reconciling Caltrans requirements, the needs of the new Presidio National Park, environmental concerns and community expectations.

In 1993, Caltrans completed a Project Study Report (PSR), which contained several alternatives for the replacement of Doyle Drive and took into consideration the recommendations of the Doyle Drive Task Force. The PSR was the first step toward securing state funding for the project.

In 1996, the Transportation Authority completed the Doyle Drive Intermodal Study, which called for the following features for the multimodal replacement project:

• 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 toll collection, 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 Authority's Board of Commissioners unanimously selected the Presidio Parkway as the Preferred Alternative. 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.
