Warren County (Friday, April 15, 2022) – As part of the interchange expansion project at Mason-Montgomery Road and southbound Interstate 71 in Warren County, a nightly road closure will be in place next week to set steel beams for the new ramp.

Beginning at 7 p.m. Tuesday, April 19, contractors for the Ohio Department of Transportation will close the right lane of eastbound Fields-Ertel Road to unload structural steel beams. Then, at 11 p.m., Fields-Ertel Road will be closed until 5 a.m. Wednesday, April 20. 

The evening and overnight restrictions will be in place each weeknight through Friday, April 22, and during periods of closure, traffic will be detoured via Escort Drive and Mason-Montgomery Road. All work is contingent upon weather.

The total project includes construction of an entrance ramp from Mason-Montgomery Road to I-71 South; a new bridge over Fields-Ertel Road; a new southbound turn lane on Mason-Montgomery from Escort Drive to the ramp; and an entrance taper on I-71 South, between the Fields-Ertel Road bridge and the existing ramp from Fields-Ertel.

The Eagle Bridge Company was awarded a contract for approximately $4.7 million to undertake the project, and all work is scheduled to be completed by late spring of 2023.
