Mark Thomas Supporting Solano Transportation Authority in Finalizing PS&E for I-80/I-680/SR 12 Interchange Improvements

Our team is proud to continue supporting the Solano Transportation Authority (STA) for the preparation of final PS&E for the I-80/I-680/SR 12 – SR 12 (West)/Red Top Road/Business Center Drive (Package 5), a part of the ongoing efforts for the I-80/I-680/SR 12 Interchange Complex.

I-80 is a major transcontinental corridor and functions as a primary commuter route within Solano County and nearby Bay Area counties. The route also provides an important connection between the Bay Area, Sacramento, the Sierra Nevada, and Lake Tahoe regions, and connects truck routes to the Port of Oakland, contributing to the economic health of the State through goods distribution in the western U.S. The Project involves extending Business Center Drive from its current terminus to a realigned Red Top Road.

This extension includes the construction of a new partial interchange on SR 12 (West) at Red Top/Business Center, as well as a reconstruction of the I-80/Red Top Road interchange. Improvements are designed to reduce congestion, accommodate anticipated increases in traffic, and address safety concerns along the existing interchange.
