TELEGRAPH ROAD CULVERT REPLACEMENT PROJECT
Telegraph Road is closed for three weeks beginning Monday, September 29, in the City of Monroe.
Local Businesses Remain Open and accessible on either side of the culvert. While Telegraph is completely closed to the thru-traffic, all businesses around the full closure (between Holiday and Greenfield) will still be accessible. When you see a road sign that says “Closed to Thru Traffic,” like the one at Stewart Road and Telegraph, it means the road is temporarily closed to drivers just passing straight through.
Local Access Remains Open. If you are visiting a business or destination along the closed road, you are still allowed to enter and drive to that location. All businesses along the route remain accessible.
The Michigan Department of Transportation (MDOT) has begun a critical infrastructure project on US-24 (Telegraph Road) at the Mason Run Drain. This work involves replacing the aging 1970s culvert, relocating essential utilities (sanitary sewer and natural gas), and preparing for future sidewalk expansion in front of local businesses. This will necessitate the full closure of Telegraph Road between Greenfield and Holiday for and estimated three weeks.
CLOSURE LOCATION:
- Telegraph Road between Greenfield and Holiday
CLOSURE DATES:
- Full closure begins at 12:01 a.m. on Monday, September 29, and is anticipated to last until midnight on Sunday, October 19, 2025.
- Anticipated road reopening on Monday, October 20 - weather permitting.
- Isolated lane closures leading up to the closure (week of September 22) will occur for signage,
staging, etc.
A three-week closure allows the project to be completed and the roadway fully reopened in the most efficient manner. Without a full closure, construction could extend into 2–3 months, creating greater disruption and overlapping with the holiday shopping season.
This MDOT project is vital as it replaces the aging culvert carrying US-24 over the Mason Run Drain. The current structure, built in the 1970s, requires replacement to ensure long-term structural integrity.
Traffic will be impacted, so plan ahead! Expect extra congestion and delays; allow extra travel time and consider alternative routes.
Please follow posted signs and traffic directions to keep drivers, pedestrians, and workers safe.
