MOT-75-11.01 (Phase Ib) I-75/US 35 Urban Interchange Widening
Dayton, Ohio
The reconstruction of Interstate 75 in the city of Dayton, Ohio, was one of the highest priorities undertaken by the Ohio Department of Transportation (ODOT) and Miami Valley Regional Planning Commission (MVRPC). The I-75/US 35 interchange was a complex, fully-directional interchange with four flyover ramps. Approximately 140,000 vehicles squeeze through this subcorridor every day. During rush hour, traffic backups had caused major congestion, idling, and accidents. Merging across lanes to exit used to be nearly impossible, and bumper-to-bumper traffic jams pushed impatient drivers to side streets, causing unnecessary wear and tear on local roadways. Several left-hand entrance and exit ramps existed in this section, along with inadequate ramp spacing. In addition, drivers were often confused because there was only one continuous lane through downtown Dayton.
To alleviate these problems, ODOT District 7 launched the $483 million I-75 Modernization Plan, a three-phase project to ensure smoother, safer traffic flow through the city while creating one primary ramp to access downtown Dayton.
