One of the busiest highway exits in the region may be a little more congested starting Tuesday and lasting for the next three months.

Ohio Department of Transportation officials say one eastbound lane of Ohio 725 will be closed through November, just east and west of the I-75 interchange. Traffic will be maintained, but with more cars squeezing into fewer lanes.

The lane closure will stretch from Byers Road (the first traffic light west of the exit ramps) under I-75 to Mall Woods Drive, which is the first traffic light east of the exit ramps.

ODOT said construction crews will be doing utility work in the area “in preparation for intersection safety and aesthetic improvements.”

ODOT spokeswoman Loryn Bryson said after the utility work is finished, safety updates will include pedestrian sidewalks and wrong-way detection systems.

This interchange had been scheduled to be converted into a “diverging diamond” style exit, but Bryson confirmed that move is still on hold for now.

A diverging diamond eliminates having drivers turn left in front of oncoming traffic by using the opposite side of the road (driving on the left) to get to and from the highway ramp.

The Ohio 725 and I-75 interchange area previously had one of the higher crash rates in the state, according to ODOT. The city of Miamisburg worked with ODOT to re-time the traffic signals in the area, which ODOT says has improved traffic flow.

A traffic configuration known as a diverging diamond interchange had been planned for the Interstate 75 and state Route 725 interchange to relieve congestion and reduce crashes. As of July 2023, it is on hold. CONTRIBUTED
