US 50/CO 115 Roundabout in Penrose

About the Project:

State-funded FASTER traffic and roadway improvement project at the intersection of U.S. Highway 50 and Colorado Highway 115 in the Town of Penrose. The goal of the project is to improve safety and traffic flow to the eastbound US 50 on and off ramps and to CO 115 by adding a roundabout.

The roundabout will be on the south side of CO 115 and intersect with the eastbound on and off ramps of US 50.

Other work includes adding a concrete island and truck apron, and installing curb and gutter, lighting, and traffic signs.

Project Benefits

  • Improve safety and traffic flow
  • Replace the intersection with a roundabout which has proven to be a safer and more efficient method of traffic operations at certain intersections
  • Accommodate trucks and wide loads with a wide turning radius/truck apron area
  • Add lighting and traffic signs

Work Schedule:

  • Work began in early March and will last for 140 working days or approximately 8 months
  • Working hours 7 a.m. to 5 p.m. Monday to Friday
  • Some overnight and weekend work is expected

Traffic Impacts:

Motorists can expect the following impacts during the period of construction:

  • Motorists can expect 24/7 lane closures on CO 115 during construction of the roundabout
  • These 24/7 closures will begin on the southbound side, followed by the northbound side, managed by temporary signals
  • The temporary signals will be installed on each end of the roundabout area to manage alternating directions of traffic into the open lane
  • No immediate lane closures are expected on eastbound US 50
  • An onsite temporary detour will be in place this spring from the eastbound US 50 off ramp to CO 115
  • The project limits on US 50 extend from MP 289.50 to MP 289.84
  • The project limits on CO 115 extend from MP 12.76 to MP 14.01
  • Construction schedules are weather dependent and subject to change
  • Refer to for real-time travel conditions and road closures
