Warren County (Wednesday, August 10, 2022) – Restrictions will be in place on Fields-Ertel Road next week as part of the interchange expansion project at Mason-Montgomery Road and southbound Interstate 71 in Warren County.


Beginning at 7 p.m. Sunday, August 14, evening and overnight lane closures will be in place on Fields-Ertel Road under I-71. Contractors will start lane closures on the eastbound right lane, and work their way across the road as work is completed.


The closures will be in place each night through Saturday morning, August 20, and all restrictions will be lifted by 6 a.m. the following day. Traffic will be maintained through the work zone.


Along with a new bridge over Fields-Ertel, the total project includes construction of an entrance ramp from Mason-Montgomery Road to I-71 South; 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.
