FOR IMMEDIATE RELEASE

Ramp, Lane Closure Scheduled Overnight as 101 NB Central San Rafael

Harbor Bridge Replacement Continues in Marin County

Ramp closure Monday, Oct. 31, Tuesday, Nov. 1 and Thursday, Nov. 3

MARIN COUNTY — Caltrans is continuing the Harbor Bridge Replacement Project in October and November for pavement and electrical work on the northbound 101 off-ramp to Central San Rafael. The project started in February 2021, and on Dec. 11, 2021, was suspended due to environmental regulations for in-creek work.

There is a full off-ramp closure of the Central San Rafael exit on US-101 northbound Monday, October 31, Tuesday, November 1 and Thursday, November 3 from 11 p.m. until 6 a.m. each night. Work will include pavement striping and other construction activities.

 

Primary detour

Continue on northbound US- 101 and take the northbound loop off-ramp to San Pedro Road

Take a right on Merrydale Road

Get on the US-101 southbound onramp

Take US-101 south to Mission Avenue

Continue onto Hetherton Street

Take a left on 2nd Street

 

Secondary detour

From northbound US-101, take the Francisco Boulevard exit

Take a right on Bellam Boulevard Take a left on Francisco Boulevard Take a right on Grand Avenue

A lane closure is scheduled from Monday, October 31 through Friday, November

4 from 9 p.m. until 7 a.m. each night. Upon exiting the Central San Rafael off- ramp, one lane (out of three) will be closed during construction; the other two lanes will remain open.

All Harbor Bridge construction work is dependent on weather this fall. Work on the intersection improvements started in May 2022 while in-

creek work resumed in June 2022 to complete the western portion of the new

bridge and switch to the final traffic configuration. The deck of the western portion of the new bridge and the bridge approach slab have been completed. The project is expected to be completed in the fall of 2022.

 

Changeable message and directional signs will be in place to assist motorists traveling in the area. The California Highway Patrol (CHP) will be on-site during the closures.

Please drive with caution. Slow for the Cone Zone and Be Work Zone

Alert. Caltrans thanks motorists for their patience while we work to maintain our state’s highways, bridges, and tunnels.
