Unfortunately, these activities are not always fully compatible. However, Iowa Department of Transportation officials say that with a little planning, you can minimize the effect road work has on your travels. The first item to take into account is where work is underway. Westbound traffic is being restricted to a single outside lane, partially located on the existing shoulder, which is separated from the work area by temporary concrete barrier rail.
Eastbound traffic is unaffected by the construction.
At two locations involving bridges over I-680, traffic will be restricted to one lane during the holiday weekend. At these locations traffic is separated from the work areas by temporary concrete barrier rail during the Memorial Day holiday. The eastbound on and off ramps to Iowa 141 are both closed. Two lanes remain for both eastbound and westbound traffic in this area for the summer. Work on this project will continue for the entire construction season.
