Presidio Tunnel Tops Project Lab


​Twenty-five years ago, visionary Bay Area leaders, urban planners, and citizens were faced with replacing the seismically unsafe Doyle Drive, a highway to the Golden Gate Bridge that divided the Presidio's waterfront from its historic core. The community did not seek simply to rebuild a freeway – it dreamed of moving the road underground into tunnels so that a powerful new experience of the Presidio and San Francisco Bay could take shape above.

Today, Doyle Drive has given way to the elegant Presidio Parkway. Through the Presidio Tunnel Tops project, we're poised to create a beautiful 14-acre green space atop the new roadway tunnels and in the surrounding landscapes – replacing a freeway with free play.

The Presidio Tunnel Tops will be San Francisco's great escape, a place where visitors will connect with nature and the outdoors, where kids will play and grow, and where all of us will be inspired by 360-degree views that were never before possible. The Presidio Tunnel Tops will be where we can find refuge from the stresses of urban life without ever leaving the city we love.
