Anticipated Traffic Impacts

During construction, motorists can expect:

  • Daytime 20-minute I-70 traffic holds for rock scaling and rock blasting resulting in delays of up to 45 minutes
    • 9 a.m. to 3 p.m., Mondays through Thursdays
    • 9 a.m. to noon, Fridays
    • Expect intermittent traffic holds on Central City Parkway, County Road 314, US 6 and US 40
  • Daytime and nighttime single and double lane closures
  • Temporary traffic shifts resulting in new traffic patterns
  • Temporary on- and off-ramp closures
  • Periodic overnight detours in the I-70/US 6 interchange and short-term closures of I-70 for safety critical work
  • Reduced speed limit as low as 45 MPH through the work zone
  • Narrower lanes and shoulders adjacent to concrete barrier
  • Trucks entering and exiting the work zone (do not follow them into the work zone)
  • Long-term closure of the Clear Creek Greenway Trail

Efforts to keep I-70 moving during construction include:

  • Keeping all lanes and ramps open during peak travel hours
  • Ensuring lane closures are responsive to current traffic patterns
  • Innovating complex work above the roadway so it doesn’t impede traffic
  • Building new roadway sections adjacent to current lanes to keep traffic moving
  • Coordinating with nearby and other I-70 Mountain Corridor projects
  • Coordinating and meeting regularly with emergency first responders
  • Providing emergency pull-off areas
  • Promoting the use of transit and carpool options to reduce low occupancy vehicles on I-70
