Project at Ohio 725, I-75 is expected to cost $8.75M and start in spring 2023.

The Ohio Department of Transportation is seeking public comments about plans to address one of the state’s most accident prone and congested corridors at the interchange of state Route 725 and Interstate 75 in Miami Twp.

“The purpose of this project is to address conditions within the corridor that are contributing to the high crash rate and to improve traffic operation,” said Josh Conley, lead roadway designer for JMT, during a project presentation video posted on YouTube.

Between 2016 and 2018, there were 170 crashes, including one fatality and 38 injury crashes. The most common type of crash involved rear-end collisions and those making left turns, Conley said.

Plans call for converting the traditional diamond interchange to what is called a diverging diamond interchange. What makes it different is that it eliminates drivers turning left in front of oncoming lanes of traffic by using the opposite side of the bridge to get onto the highway ramp.

A traffic configuration known as the diverging diamond interchange is planned for the Interstate 75 and state Route 725 interchange to relieve congestion and reduce crashes. CONTRIBUTED

An area example of this is at the Union Centre Boulevard and I-75 interchange in West Chester Twp. that was recently completed.

Other plans to the interchange include making upgrades to the traffic signals between the state Route 725 and Byers Road intersection and the state Route 725 and Mall Woods/Prestige Plaza intersection and to install a sidewalk from Byers Road to state Route 741, according to ODOT.

Total project cost is estimated at $8.75 million and is expected to take eight to 10 months to complete. The time frame calls for construction to begin in the spring of 2023 and for work to be finished during the fall of 2023. Traffic would be maintained during construction, Conley said.

The ODOT project is in cooperation with the Montgomery County Transportation Improvement District, the cities of Miamisburg and West Carrollton and the Miami Valley Regional Planning Commission.

Questions and feedback are requested no later than June 16.
