The closure will occur from Monday through Friday from 10 p.m. to 6 a.m. nightly, and also from Tuesday, Sept. 3, through Friday, Sept. 6 during the same hours. Further closures of that on-ramp are planned from 10 p.m. to 9 a.m. on Sept. 6-7, and Sept. 9 through Sept. 13, Caltrans said.
The overnight maintenance will require motorists to detour across the Richmond-San Rafael Bridge, exit at Main Street and re-enter the bridge to return in the eastbound direction.
