The new Presidio Tunnel Tops is a unique project located in San Francisco, California that includes an expansive landscaped park spanning over the top of the newly built Doyle Drive tunnels. It also includes the Crissy Youth Center buildings/classrooms, a learning landscape, restroom buildings, and various site features. The Presidio Tunnel Tops is a new focus of the Presidio — one that affords magnificent 360-degree views in all directions and links the Presidio parade grounds to Crissy Field at Mason Street, south of Crissy Field Marsh.
The historic south access road to the Golden Gate Bridge, previously known as Doyle Drive or Route 101, had reached the end of its useful life and was structurally and seismically deficient. Replacing the aging roadway was critical for traffic safety and also provided an opportunity for major design improvements. Doyle Drive has been re-envisioned as the Presidio Parkway — a roadway tucked into the natural contours of the Presidio and the Golden Gate National Recreation Area. The approximately 14-acre Presidio Tunnel Tops project extends over the top of these recently constructed tunnels and includes extensive native landscaping, specialty paving, recreational elements, and intricate site structures.
