Caltrans will be closing Highway 116 under Highway 101 in Cotati this weekend to allow construction crews to remove supports used in widening the overpass there.
The closure will be 6 p.m. Saturday to 5 a.m. Monday, but it will not affect Highway 101’s on- and offramps.
Drivers will need to detour north to Rohnert Park Expressway to cross over 101.
