SMART construction crews are scheduled Saturday to have closed Main Street in Penngrove at the railroad tracks.
The road is to reopen at 9 p.m. Saturday.
The closure is part of the rail district’s upgrade of the tracks through Sonoma County. Crews are tearing out old crossings and putting in new track and smooth crossings. To do so, they need to shut all lanes at each crossing day and night.
