20-mile stretch of I-70 in eastern Arapahoe County to get new pavement

Project Update

March 4, 2024 - Central Colorado - CDOT begins work in early March

Arapahoe County — Work begins March 4 to remove and replace deteriorated pavement on a 20 mile stretch of I-70 from Bennett to Deer Trail in Arapahoe County. The project is scheduled for completion in late May. The Colorado Department of Transportation is delivering the project with Ralph L Wadsworth Construction CO LLC.

The pavement reconstruction involves replacing concrete panels, requiring single lane closures along I-70.

Traffic impacts

  • Starting March 4, single lane closure in a one-mile increment in one direction of I-70 from 7 a.m. Monday to noon Friday each week until the project is done in late May. There will be no lane closures during the weekends, holidays or adverse weather conditions.
  • Work begins on westbound I-70 near Deer Trail. There will be a single lane closure for a length of one mile. Once panels are replaced in that mile-long segment, then the single lane closure will shift for another mile increment in the westbound direction.
  • After panels are replaced on the westbound side from Deer Trail to Bennett, then crews will shift to the eastbound side, with a single lane closure beginning at Bennett.
  • Motorists should be prepared for minimum traffic impacts with possible delays during the morning and evening peak travel periods.
  • Speed limit in the work zone will be reduced to 65 mph.
  • It's extremely important that motorists pay close attention while traveling in the work zone, heed the speed limit, leave ample following space and watch for crew members.
  • Refer to COtrip.org for real-time travel conditions and road closures.

Why is the project needed?

The original pavement was built in 1991. The I-70 driving surfaces are deteriorating, requiring multiple repairs. They need to be permanently replaced for the long-term safety of the traveling public and will also improve driving surface conditions.
