WINDSOR — Traffic on the Route 5 bridge that carries traffic over Mill Brook will be reduced to one lane this week between 9 a.m. and 4:30 p.m., to allow for bridge inspections, according to a VTrans traffic advisory.

Southbound vehicles will be rerouted from Route 5 to Union Street, also known as Route 44.

The state’s detour ends at the intersection of Route 44A and Route 5, which is located in Ascutney, nearly four miles to the south.

Northbound travel will not be affected by the closure, the advisory said.
