Presidio Parkway Project, San Francisco, CA
Project Dates: 2011-2012
Client: San Francisco County Transportation Authority (SFCTA) and Caltrans District 4
Cost: $147 Million
Project Description: The Presidio Parkway Project reconstructed approximately 1.6 miles of the existing U.S. 101 from the south approach to the Golden Gate Bridge to Richardson Avenue and Marina Boulevard near the Palace of Fine Arts in San Francisco, CA. This parkway provides a vital transportation link between the North Bay counties, San Francisco, and the Peninsula. The Presidio Parkway Project improves structural, seismic, and traffic safety along this section of U.S. 101, while also creating a roadway that reduces impacts to biological, cultural, and natural resources.
Services: PARIKH Consultants, Inc. prepared a geotechnical investigation for the design of a tunnel, several bridge structures, and retaining walls along Presidio Parkway. As a part of the Geotechnical team, PARIKH was responsible for foundation reports on the northbound Battery Tunnel and Viaduct. The firm also performed northbound and southbound final foundation reports at Tennessee Hollow. The project was on a very aggressive schedule and the Public-Private Partnership (P3) program required consensus from stakeholders. The project had to meet environmental requirements, Presidio Trust conditions, and Caltrans design specifications. Multiple design changes were mitigated effectively and in a timely manner. All work was completed on time, within budget, and according to Caltrans standards.
