Project Benefits

Benefits for motorists from these maintenance repairs include:

  • Smoother, more comfortable road surface, making travel safer for vehicles, especially in inclement weather
  • Better drainage and weather resilience, preventing clogging from debris and helping avoid water pooling, hydroplaning risks or flooding
  • Extended lifespan of existing structures, potentially delaying or avoiding more extensive and disruptive repairs or full replacements
  • Repaired and updated joints improve infrastructure efficiency and environmental impacts

Work Schedule

Daytime work hours range from 7 a.m. to 5 p.m., Monday through Friday.

Traffic Impacts

  • US 160 bridge over the Rio Grande river will be reduced to one lane of alternating traffic until early June
    • A width limit of 10 feet 0 inches will be in effect.
  • Motorists should plan for lane shifts and lane reductions
  • Two-way traffic will be maintained throughout the project
  • Debris removal will be conducted so that the traveling public is protected and traffic impacts are minimized
  • Motorists are advised to drive with extreme caution through these areas as the travel lanes will be narrower and crews with heavy equipment will be working in the area
  • Minor traffic delays are expected
  • Refer to COtrip.org for real-time travel conditions and road closures
