I just got an email from Assistant Town Planner Vanessa Hale saying CSX needs to do some emergency repair work tomorrow on the railroad tracks that cross Main Street in downtown Southborough. The road will be down to one lane for most of the day on Friday, and will be closed entirely for one 3-hour stretch.
No information on when the work will begin, or when the 3-hour closure will happen. The police are scheduled to have a detail at the site from 8:00 am to 4:00 pm, so that at least gives a general range.
Suggested detour routes are Latisquama to White Bagley, or Newton Street to Marlboro Road.
Update: Just got an update. The work is from 9:00 am to 2:00 pm.
