The state Department of Transportation has announced that it is postponing a detour and closure of Route 1 in Old Saybrook. A new date has not yet been announced.

The detour originally was scheduled to take place from 7 p.m. Sept. 29 to 5 a.m. Oct. 4 as DOT works to replace the Route 1 bridge over Center Brook.

The construction project calls for the "replacement of the bridge with a precast box culvert and precast wingwalls," according to the news release. The project will begin with the relocation of existing utilities and the reconstruction of the east and west approaches to the bridge. It will include drainage and roadway improvements, as well as improvements to signalization at the intersection of Route 1 and Center Road.

The project was awarded to LaRosa Earth Group LLC for $1,079,219.40.
