Vermont transportation officials say construction on the Checkered House Bridge in Richmond will force some brief road closings – including part of Interstate 89.
Blasting is needed for construction of a temporary detour for Route 2 as it passes over the Winooski River.
Starting Tuesday, there will be two blasts per day – one at 11 in the morning and one at in the afternoon – on weekdays for up to four weeks.
During the blasting period, no traffic will be allowed into the blast zone. Vermont State Police will manage "rolling roadblocks" with traffic stoppages of up to 10 minutes apiece on the affected roads, which include Interstate 89 between Exit 11 in Richmond and Exit 12 in Williston, Johnnie Brook Road, Kenyon Road, Route 2 and Route 117 in the area of Route 2.
