CO 60 Chip Seal Project set to begin May 18

Project Announcement

May 12, 2026 - Northeastern Colorado - Work will occur between US 287 and I-25

Larimer and Weld counties — The Colorado Department of Transportation will begin a chip seal project on May 18 along Colorado Highway 60 in northern Colorado. Chip seal work will take place from US Highway 287 to Interstate 25, Mile Points 0 to 4.83. The project is expected to be completed by late June.

The work will include a chip seal, which is a two-step process that includes first an application of asphalt emulsion and then a layer of crushed rock to an existing asphalt pavement surface. A-1 Chipseal Co., of Denver is the contractor for this project.

Chip sealing is a cost-effective surface treatment method of pavement maintenance and rehabilitation. The chip seal project will preserve the existing roadway surface quality and extend the total service life of the pavement.
