The Colorado Department of Transportation and contractor Intermountain Slurry Seal are pleased to announce the completion of the surface treatment project on US Highway 160/491. The project took place on US 160/491 from Mile Point 29.75, 2 miles north of Towaoc and continued for more than five miles to MP 34.89 near Cortez. The southern limits of the project adjoin the US 160/491 Towaoc passing lanes project that was completed earlier this year.

As part of CDOT’s Whole System – Whole Safety initiative, this project focused on a chip seal and micro-surfacing application that included three thin layers of resurfacing to protect and prolong the surface of the roadway and reduce overall cracking in the existing asphalt. Interfacing these three layers of oil and rock creates a strong and flexible mat that will preserve the existing asphalt beneath.

The new surface will enhance safety for motorists by providing a smoother surface for vehicles. Crews also installed rumble strips and new striping. The new striping will offer better visibility, while rumble strips will alert drivers if they are leaving or veering off the roadway or lane.
