The Connecticut Department of Transportation says the Route 7 south exit ramp to I-95 south in Norwalk will be closed nightly from 9 p.m. to 5 a.m. Monday through Friday from Monday, April 21 through Friday May 2, weather permitting.
Traffic will be detoured onto the West Avenue (South Norwalk) exit and re-enter I-95 southbound at the West Avenue on-ramp.
The closure is to allow for installation of drainage improvements along and across the ramp. It is part of a project to build continuous auxiliary lanes (referred to as speed change lanes) between Route 1 and Route 7, and make improvements to Route 1 in Norwalk.
