Construction crews on Monday were putting the finishing touches on a Jefferson Avenue repair project that became necessary after new catch basins on the busy street were installed incorrectly. The drainage basins were originally added months ago as part of a $3.9 million state- funded project paid with Local Transportation Capital Improvement Program, or LOTCIP, funds administered through the Southeastern Connecticut Council of Governments. The initial work meant digging up and rebuilding roughly 2,500 linear square feet of Jefferson Avenue and construction of a “three-legged” roundabout near the high school, with new sidewalks, crosswalks, lighting and curbing. But several weeks ago, after paving was completed, an inspection showed undulations in the road in the areas of the basins, Director of Public Works Brian Sear said. Ultimately, the tops of 12 basins were lowered by about three inches using a combination of more compactable concrete and flatter basin tops. Final sealing work on the repair job was being conducted Monday morning.
