Presidio Parkway (Doyle Drive replacement) Rte 101 at Golden Gate Bridge, San Francisco County, CA

Doyle Drive has been re-envisioned as the Presidio Parkway – a roadway tucked into the natural contours of the Presidio of San Francisco and the Golden Gate National Recreation Area, one of the nation’s largest urban parks. The new Doyle Drive, which reopened on July 12, 2015, serves as a regional gateway between the iconic Golden Gate Bridge and the city of San Francisco.

As a part of the team, PARIKH conducted the geotechnical investigations for the Northbound Battery Tunnel, High Viaduct, bridge structures, and retaining walls. The project included several roadway grade separations, cut and cover tunnels, and embankments including tall retaining structures.
