The Connecticut Department of Transportation (CTDOT) is alerting the public that the replacement of the railroad crossing on Route 123 (New Canaan Avenue) in Norwalk is scheduled to take place August 1-5, 2025 and will require full closure of Route 123 directly at the railroad crossing for approximately 120 hours.
The existing railroad crossing is being completely replaced with all-new materials to enhance safety, provide smooth passage for motorists, as well as ensuring the long-term viability of passenger and freight rail service in the region.
“This is an important project that ensures the rail crossing is safe for our passenger rail services and the public,” said Connecticut Department of Transportation Bureau Chief of Public Transportation Benjamin Limmer. “We appreciate the community’s patience during construction this summer and ask them to follow the posted detours or seek alternate routes to ensure safe travel.”
The work to replace the railroad crossing will require vehicular and pedestrian detours during construction to ensure workers and the public remain. Detour signage will be posted to bypass the work zone. All businesses and residences will remain accessible throughout the short-term construction project.
Given the volume of traffic normally associated with the area, it is recommended that those who use Main Street/New Canaan Avenue solely as a connector between the Merritt Parkway and US Route 7 to avoid the area and seek other regional bypasses. Those traveling through the area should use caution and plan extra time.
This project is funded by CTDOT, and performed by Metro-North Railroad, in coordination with the City of Norwalk, First Responders, bus and transit providers, and other stakeholders. Extreme weather may alter the work schedule.
