Project Purpose
The purpose of the Route 7/15 Norwalk Project is to improve roadway system linkage between Route 7 and Route 15; improve the mobility for all users (motorists, pedestrians, and bicyclists) at the Merritt Parkway’s Main Avenue and Route 7 Interchanges; and improve safety in the vicinity of these interchanges.
The current Route 7 /Route 15 (Merritt Parkway) is a partial interchange. The missing connections cause traffic congestion and delays on Main Avenue and other local roads. Missing connections include:
Route 7 North to Route 15 North
Route 7 South Route 15 North
Route 15 South to Route 7 South
Route 15 South to Route 15 North
Project History
The reconstruction of the interchange at the Route 7 and the Route 15 (Merritt Parkway) interchange started in 2005 when litigation resulted in stoppage of work, ultimately followed by cancellation of construction in 2006. Construction cancellation was the result of a finding by the court that the project records did not demonstrate that avoidance, minimization and mitigation alternatives associated with impacts to historic features had been adequately analyzed.
