Caltrans is temporarily shutting down ramps on Highway 101 in preparation for shifting southbound traffic onto the new Petaluma River bridge.

The north and southbound offramps to Petaluma Boulevard South/Kastania Road will be closed from 9 p.m. to 5 a.m. today, Friday, Saturday and Sunday.

Similar ramp closures are scheduled in the area of southbound 101 at Lakeville Highway.

The new Petaluma River bridge will be wide enough to accommodate three lanes of traffic in each direction plus standard shoulders. At 907 feet long with a 212-foot main span between pillars, it will be the longest bridge of its kind in the western United States.
