Lane reductions along Highway T-17 from Highway 92 to Highway 163 will begin today for the Iowa DOT to patch the highway ahead of a bridge replacement project in Mahaska County. Delays can occur on Elevator Road for one-lane traffic to prepare T-17 for detour traffic related to a replacement of the Iowa Highway 92 bridge over Muchakinock Creek later this construction season west of Oskaloosa. The patching work on the county highway is expected to continue until Friday.
