There’ll be night-time closures for a heavily-traveled portion of Interstate-80 in eastern Iowa for the next few weeks. Mark Brandl, the resident construction engineer in the D-O-T’s Davenport office, says sections of the roadway will be removed and replaced. Brandl says the pavement has deteriorated, primarily at what he calls the “joint.” The “joints” are where the “cuts” are in the paving. Brandl says pavement is built in sections to control cracks. There’s reinforcing steel in the joints, and oftentimes that’s where the cracks start. Brandl says the repair work will be done by early September and won’t affect traffic to the Iowa Hawkeye football games. Brandl says crews won’t work overnight Friday into Saturday morning, or on Saturday night into Sunday morning, so it shouldn’t clog up I-80 on game days in Iowa City. The pavement patching project will start in Iowa County, then continue east along I-80 into Johnson and then Cedar Counties.
