Travel Advisory

April 3, 2024 - Southwestern Colorado - Motorists are reminded to drive slow to avoid damage from loose stones

La Plata County — On April 8, the Colorado Department of Transportation will begin week-long chip sealing operations along a 7-mile segment of Colorado Highway 172 between the New Mexico state line and the junction of County Road 318. Motorists traveling CO 172 south of Ignacio, Mile Points 0 - 7, will encounter brief delays and full stops guided by a portable light signal.

CDOT crews will work as swiftly as possible to complete the surface treatment however resurfacing operations are weather dependent.

Traffic Impacts

Daytime work hours range from 7 a.m. to 4:30 p.m. Monday through Friday.

  • Motorists should plan for 10-15 minute delays and should allow for extra travel time
  • Expect one-lane alternating traffic guided by signs, pilot cars and portable light signals
  • A speed reduction of 40 mph will be enforced through the work zones

Travelers driving through surface treatment projects are urged to:

  • Slow down ― Higher speeds can cause loose stones to scatter and damage vehicle paint and windshields
    Increase distance between vehicles ― Space between you and other vehicles will help reduce damage caused by loose stones
  • Follow work zone signage, signals and flagging personnel ― Consider the safety of other motorists and the safety of the work crew when traveling through the project construction zone
  • Use caution ― Bicyclists and motorcyclists should use extreme caution during construction operations
