This Ohio Department of Transportation (ODOT) project was constructed on State Route 29 (SR 29) at Interstate 70 (I-70) in Jefferson Township and the Village of West Jefferson in Madison County, OH, USA. The project included a new SR 29 bridge over I-70, a second roundabout at the SR 29 intersection at the I-70 eastbound exit/entrance ramps, pavement widening, drainage improvements, and the addition of a second lane to the existing roundabout at SR 29 and I-70. Slag cement was used in the concrete mixtures to achieve low permeability and high albedo.

I love how the new interchange and roundabout design prioritizes safety while managing traffic flow! It reminds me of my hometown’s recent upgrades, where we saw an astonishing decrease in accidents. It's fascinating to see engineering evolve for better community experiences. Excited to see it in level devil action on IR 70!
