Garfield County — Construction crews will soon be back from a winter shutdown to resume work on Colorado Highway 13. The Garco Rio Blanco Hill project is located 11 miles northwest of Rifle and will create safety improvements for the busy stretch of highway. The start date for work in April is weather-dependent. The project is part of CDOT’s statewide 10-year plan to improve highways across Colorado.

Safety improvements on the project are designed to give motorists wider roads to travel on during inclement weather, accommodate higher traffic volumes, and to help prevent roadside erosion. The resurfacing and widening will create smoother pavement and improved driving conditions, and adding chain up areas will significantly improve safety for travelers when weather conditions suddenly change. Two wildlife underpasses will help reduce wildlife-vehicle collisions.

During the 2022 construction season, crews completed the installation of box culverts and 72” jacked steel pipes. Other items completed were asphalt patching and the relocation of the CDOT Intelligent Transport System (ITS).

The project team will stay in close contact with CDOT maintenance crews in the event of Interstate 70 closures in Glenwood Canyon. This coordination will help the project team prepare for detour traffic during I-70 closures.

Beginning early April, crews will begin work to complete the headwall structure at 72-inch jacked pipe, storm drainage crossings, game ramps, wildlife fencing/animal crossings, concrete lined ditch, geosynthetic reinforced soil (GRS) wall, barrier walls, cattle/deer guards, aggregate base course, asphalt paving, roadway mitigation, storm drainage completion, permanent signage, permanent striping, and new guardrails. The anticipated completion date is fall 2023.
