History

I-74/I-275 bridge crash

On May 20, 2008, a tractor-trailer hauling a locomotive separated while traveling on the ramp from westbound

to southbound I-275. After the trailer detached, it crashed into supports for the bridge on I-74 eastbound going over the ramps between I-275 and I-74 westbound. As a result, the Ohio Department of Transportation (ODOT) shut down eastbound I-74 for several weeks. Both ramps between I-74 west and I-275 were closed as well because of fears the bridge would collapse, but two crossovers were built so that traffic could use one lane of westbound I-74 to travel east around the damaged bridge.
