Presidio Parkway Technical Due Diligence
Location: San Francisco, California, USA
Presidio Parkway is the new roadway that will replace the aging south access road to the iconic Golden Gate Bridge, known as Doyle Drive or Route 101. Originally built in 1936, Doyle Drive had reached the end of its useful life. The roadway was facing the ravages of time and continual use. Replacement of this aging roadway is not only critical for seismic and traffic safety, but also provides an opportunity for major design improvements. LeighFisher provided lenders technical due diligence on behalf of potential funders prior to bid submission and technical due diligence on behalf of funders prior to financial close. Currently, we are providing construction monitoring on behalf of funders. Our services in Phase 1 covered the cut-and-cover tunnels, the Girard interchange, the Northbound Presidio interchange, and landscaping.
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 natural parks.
The Parkway will provide a spectacular regional gateway between the Golden Gate Bridge and the City of San Francisco. The project strives to reduce impacts to biological, cultural, and natural resources; respect the project setting within a national park, the National Historic Landmark District, and surrounding neighborhoods; meet community needs; and provide a safer roadway.
- Major design improvements in replacing an aging roadway through infrastructure planning and advice
- An iconic project providing a regional gateway between the Golden Gate Bridge and the City of San Francisco
- Two major phases to construction: Phase 1: achieve seismic safety by switching traffic off Doyle Drive on to Phase 1 structures (completed April 2012); Phase 2 construction of a new Northbound bridge, northbound Battery Tunnel, and associated works using a Public-Private Partnership delivery model
