Both projects are necessary to complete permanent repairs to canyon corridors impacted by September 2013 flooding. A major source of funding for transportation-related flood recovery work is the Federal Highway Administration (FHWA) Emergency Relief Program. CDOT advertised both projects for construction this season to fulfill funding timeline obligations. Federal guidelines would not allow deferral of either project to a later start date.

The CO 119 and CO 72 project teams will communicate their respective weekly construction traffic-control schedules to provide advanced notification about possible traffic volume increases. Full closures are not currently anticipated on CO 72. However, CO 72 will have multiple work zones in a single-lane configuration with alternating traffic controlled by automated signals. CO 72 traffic is also subject to flagger control at additional locations. Expect up to 20-minute delays on CO 72.

Sections of CO 119 in Boulder Canyon will be closed intermittently for rock scaling and blasting.

Learn more about the project, and to sign up for closure notifications.

All planned lane and road closures on state highways are posted in advance on COtrip.

Safety is a top priority. Bicyclists will not be allowed to travel through the work zone due to limited road width under the single-lane configuration, and to prevent traveling against the flow of traffic controlled by the temporary traffic signals. Uneven or gravel road surfaces may exist.
