Modernization of I-75 through Downtown Dayton
 

 Current Project Updates

 
All traffic is currently running on the existing northbound lanes between US 35 and Main St. The only access to Downtown Dayton is provided at US 35 and Main Street. Traffic will be in this configuration throughout construction of the new southbound lanes.  Additionally, there is a long term left lane closure on the ramp from Route 4 southbound to I-75 southbound.
 
The Project is 35.3%  Complete.

INFORMATION HOTLINE NUMBER: 937-425-8475

This project began October 8, 2012.

The ramps from I-75 Northbound to First Street and Third Street closed October 15, 2012. These ramps will remain closed.

Expect the First Street and Third Street ramps on the southbound side of the interstate to close in mid November or early December. Please see the detour map below for alternate routes. ​

This is major construction. Motorists are advised to use caution and reduce speed through the work zone.

Arrow boards and signs will be in place prior to the work zone to alert motorists of the upcoming lane closures. Law enforcement will be on site to monitor traffic flow.
