Progress continues on a six-year project that will reconstruct I-70 through the city of Zanesville, Ohio. The Ohio Department of Transportation (ODOT) is overseeing the $88 million effort, which includes major bridge work and the resurfacing of I-70 between U.S. 40 and State Route 93 in Muskingum County. “Failures of subgrade throughout the project limits and deteriorating pavement and bridge conditions have caused maintenance throughout this section to become excessive,” said Audrey Seals, ODOT area engineer, who explained that
construction will be stretched out over time. “The phasing of the project is difficult, as it is necessary to maintain two lanes of traffic in both directions, while also allowing as many ramps to be open as possible throughout Zanesville. Lane closures are only permitted during certain times, mostly at night, due to the volume of traffic that travels this section of I-70. There are 16 bridges that will be rehabilitated on this project, and some of them have limited access, so not all of them are able to be constructed at the same time.” Pre-Phase 1 work included constructing temporary concrete pavement widening, temporary lighting and installing portable concrete barrier to move traffic to the outside lanes
for the Phase 1 configuration. It also required adding advance radar detectors on various signals throughout Zanesville to improve the traffic flow through town during construction. Two temporary signals also were added at the SR-93 on and off ramps to facilitate the detours to be used throughout the project. “Phase 1 includes removing the existing median barrier and constructing new concrete barrier with the addition of new lighting on the concrete barrier,” said Seals. “It also includes reconstructing the inside lanes and various ramps, which consist of full depth reconstruction of the pavement with cement stabilization of the subgrade, as well as various see ODOT page 4
