Location: San Francisco, CA
Client: Presidio Trust
The iconic Golden Gate Bridge and its surroundings are internationally recognized landmarks. However, the existing south access road to the Golden Gate Bridge, known as Doyle Drive or Route 101, was structurally and seismically unsafe requiring replacement. Winding 1.5 miles along the northern edge of San Francisco, the roadway is the primary transit linkage through the city to the north. The project area extends on the west from the Golden Gate Bridge Toll Plaza to the Palace of Fine Arts in the east. It is also located within the Presidio of San Francisco and provides access to historic and cultural landmarks including the Golden Gate National Recreation Area.
Doyle Drive has been re-envisioned as the Presidio Parkway, boasting a world-class design that will improve the seismic, structural and traffic safety of the existing roadway. Impacts to biological, cultural and natural resources will be reduced by respecting the project’s designation as a National Historic Landmark District and National Park, as well as respecting the needs of the surrounding community. Key features include four short tunnels, new access points that connect the Presidio to Crissy Field, and improved views to the San Francisco Bay. The tunnels allow Presidio users to experience the park without being aware of the highway’s presence beneath and significantly increases the amount of park space. The landscape incorporates new trails, bike paths, and connects users to all parts of the Presidio.
Creo was tasked with assisting the Presidio Trust to conceptualize the landscape surrounding the new roadway development. We worked closely with the Presidio to develop detailed sections, tunnel loading studies, grading and layout design for both tunnel top parklands as well as the surrounding landscape.
Creo developed some conceptual landscape designs for the Main Post Tunnel top which set the stage for developing our detailed documents and studies. This view depicts a promenade with concentrated activity spaces, sculpture and viewing areas.
