Overnight Closures Begin on Highway 20 in Dubuque

Overnight closures will begin tonight on Highway 20 in Dubuque.

Crews will be setting girders for the Dubuque Southwest Arterial Bridge over Highway 20. The project will require detouring eastbound Highway 20 traffic onto North Cascade Road each night for the next week and a half.

The traffic detouring will take place from 10 pm to 5 am Monday, February 11th through Thursday, February 21st weather-permitting.

During this closure, traffic will be guided around the work zone by digital message signs and a marked detour.

There will be no change to Highway 20’s westbound traffic during the night closures since they bypass the bridge. Westbound traffic will continue using the ramps to detour around the work zone as they have been for the past year.
