Alert: Salem Avenue Bridge, First & Second Streets Reopen
According to the City of Dayton, First and Second streets downtown and the Salem Avenue Bridge have reopened as work on that portion of the I-75 modernization was completed.
Alert: Temporary Closure Announced
According to the Ohio Department of Transportation, the following temporary closure is scheduled as part of the I-75 Modernization Project through downtown Dayton:
- Red Cross Lane between First Street and Gibbs Lane - 24-hour road closure through September 1, 2016. The official detour during this closure is First Street to Perry Street to Second Street to Red Cross Lane.
Current Travel Conditions:
(As of January 2016) All traffic is running on the new southbound structures between Main Street and US 35. Access to downtown Dayton is still provided at US 35 and Main Street. Traffic will be in this configuration throughout construction of the new northbound lanes. There is a long term left lane closure on the ramp from SR 4 south to I-75 south.
All southbound and northbound I-75 ramps through downtown currently are closed. These closures are part of construction on the final phase of the I-75 Modernization Project, which will reconfigure the highway through downtown.
Drivers who previously used these ramps to enter or leave downtown should begin using one of the alternative routes. The following ramps will remain open throughout construction and serve as primary detours to access downtown:
- Jefferson Street off U.S. 35
- Main Street off I-75
- Edwin C. Moses Boulevard off I-75

The $168 million final phase of the I-75 Modernization Project will improve safety, decrease congestion, and provide much-needed updates to the more than 50-year-old highway between the intersections of I-75 and Route 4 and I-75 and U.S. 35. The project is expected to be completed in fall 2017. I-75 between Main and Fifth streets will be completely reconstructed. The project includes:
- removal of left-hand entrances and exits, replaced by one primary ramp to access downtown;
- creation of three continuous lanes in both directions from Third to Main streets and upgrading of pavement conditions;
- total reconstruction of 12 bridges;
- creation of one central interchange in the area of First and Third streets; and
- the realignment of surface streets to coordinate with revised interstate entrances and exits.
In these renderings of the completed I-75 through downtown, notice the new green space created along the river and larger, easier-to-access exit and entrance ramps at Third Street.
