Work schedule: Wednesday, Feb. 15 and Thursday, Feb. 16

MARIN COUNTY — The Marin-Sonoma Narrows B-7 construction project continues in February with restriping work on US-101 southbound in Burdell in unincorporated Marin County.

The work near San Antonio Road is scheduled for Wednesday, February 15 and Thursday, February 16 from 11 p.m. until 5 a.m. the next mornings. One lane will be closed, and one will be open.

This is the last remaining High Occupancy Vehicle (HOV) lane construction project as part of the 16-mile US-101 Marin-Sonoma Narrows (MSN) program. This 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 line, and for 6.3 miles along the southbound lanes from De Long Avenue to the county line.
