Project: Highway 101/Lakeville Interchange

This project represents another step toward having 17 miles of continuous carpool lanes through Sonoma and Marin Counties. Carpool lanes will be added, the San Antonio Creek Bridge will be replaced and a section of the highway will be moved out of the floodplain.
