The contractor is required to limit the length of the closure, and expects the work to last about three weeks.
During the closure, traffic will be detoured along Penn and Stewart streets. All businesses will remain open.
Drivers are asked to use caution around the work site, allow extra travel time, and find alternative routes when possible. Details and updates on this and other North Liberty construction projects are available at northlibertyiowa.org/projects.
Update: the Cherry Street underpass will remain open until Monday, May 14, 2018, when it is expected to close for four days.
