This final MSN project will complete and allow continuous HOV lanes on US-101 from Sausalito in Marin County to Windsor in Sonoma County. HOV lanes are scheduled to be open for use in the summer of 2025.
Construction includes widening US-101 to install HOV lanes for 3.5 miles along the northbound lanes from North Novato to the Marin-Sonoma county line, and for 6.3 miles along the southbound lanes from De Long Avenue to the county line.
