Design-Build Projects


Illinois Street Multi-modal Bridge
San Francisco, CA

Project Overview

The Illinois Street Multi-modal Bridge, crossing the Islais Creek Channel between Pier 96 and Pier 80, provides on-dock rail to the Port of San Francisco’s cargo terminal at Pier 80. It also serves as an alternative route for trucks leaving the cargo terminals in the southern part of the city and offers a pedestrian crossing. Intersection geometry, striping, and signal coordination were major challenges due to local access needs and the adjacent intersections of Third Street and Cargo Way to the south and Third Street and Tulare Street to the north.

CHS Role

CHS Consulting Group served as traffic engineer for the design-build team. CHS’ responsibilities included preliminary and final design of intersection geometry; traffic signal plans at the intersections of Cargo Way and Illinois and Amador Streets, and Marin Street and Illinois Street; and coordination with the freight rail signals. CHS also developed the design and specifications for the street lighting system. The project has been completed and is now in operation.
