Work will be rescheduled for next week. Dates to be decided.
MARIN COUNTY — Caltrans is continuing the Harbor Bridge Replacement Project in September 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 was an expected full off-ramp closure of the Central San Rafael exit on US-101 northbound from Tuesday, September 20, through Thursday, September 22 from 11 p.m. until 7 a.m. each day due to drainage and curb ramp work. However, those dates have been rescheduled for next week. Specific dates and times will be announced later.
Harbor Bridge 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 finished as early as the fall of 2022.
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.
