Travel Advisory

May 31, 2024 - Denver Metro/Central Colorado - Overnight impacts early to late June

Commerce City — The Colorado Department of Transportation will begin repairs Sunday, June 2, on the Dahlia Street bridge over I-76. The project will repair damage that was caused when a tractor-trailer, towing construction equipment, struck the outer edge of the bridge last March.

The repair work will require overnight single lane closures on I-76 June 2 through early July and a 36-hour weekend full closure of westbound I-76 under the Dahlia Street bridge in late June. Northbound Dahlia Street bridge will continue to be closed during the project. The repairs should be complete in early July.

The project involves repairing the damaged bridge girders, other bridge reconstruction and repainting. The project will fully restore the bridge to its original form and reopen northbound Dahlia Street traffic over I-76, which has been restricted since March.
