East Lyme — The state Department of Transportation has announced that it will alternate one-way traffic, using temporary signalization, on Route 1 over the Pattagansett River in town, beginning on or about Tuesday.

The project consists of a bridge structure replacement, drainage improvements, and roadway reconstruction, according to DOT's news release. Alternating one-way traffic will allow one lane on the bridge to remain open during the work.

The contract was awarded to D & V Morin Construction Co. for $1,991,519 on June 24, 2016 and is scheduled to be completed Nov. 14, according to DOT.
