US-23 and US-223 Road and Interchange Improvements, Monroe County

Start: Fall 2012      End: Fall 2013
What we are doing: 

MDOT will reconstruct northbound US-23 between Sterns Road and the US-223 interchange, along with interchange improvements and repairs to the Dundee Welcome Center.

  • Roundabouts will be added at the US-23/US-223 interchange to increase safety and improve traffic flow.
  • Work will take place in stages over two years.

How traffic is affected: 


  • Work will take place in the median along US-23 with shoulder closures and off-peak lane closures.
  • For work taking place on the Sterns Road interchange, traffic will be detoured using the Consear Road interchange and vice versa.
  • The Dundee Welcome Center will be open to passenger cars but will be closed to commercial truck traffic. Truck drivers will be directed to use truck stops along US-23 during construction.


  • Northbound US-23 will be reconstructed between Sterns Road and the US-223 interchange.
  • US-23 will have one lane open in each direction with traffic maintained on the southbound side of US-23.
  • During interchange construction, traffic will be detoured using US-23.
  • On US-223, construction will take place in stages with westbound traffic maintained at all times. Eastbound traffic will be detoured south to the Consear Road exit and back to the US-223 interchange with a temporary signal allowing motorists to turn east.
    • The eastbound detour will remain in place until the northbound off ramp is closed for approximately 30 days for reconstruction.
    • During this ramp closure, northbound US-23 traffic will be detoured north to the Summerfield Road interchange, then south to the US-223 interchange.
