Traffic Impacts

  • General working hours will take place from 7 p.m. to 7 a.m., Monday night through Friday night.
  • Additional daytime and weekend work is expected intermittently.
  • Motorists will encounter single-lane closures on CO 157 during weeknights, with one lane of traffic open in each direction.
  • Initial concrete panel replacements require weekend work in addition to weeknight operations. Motorists can expect various nighttime and daytime closures for the first six to eight weekends of the project.
  • Full closures are expected during several weekends on CO 157. These will occur one direction at a time and during weekends only to reduce impacts to weekday commuters.
  • Alternate routes are advised during peak travel times and periods of full directional closures.
  • The Pearl Parkway on and off-ramps at CO 157 will experience intermittent closures with detour routes. These closures are expected to be minimal throughout the project’s duration.
  • While significant delays are not anticipated, motorists are encouraged to account for up to 10 minutes of extra travel time.
  • Please be aware of additional ongoing road construction projects in the area. Teams will coordinate closures to minimize impacts to the traveling public.
