Central 70 Construction Ramps Up

Oct. 1, 2018 - Expect Local Road Closures, Interstate Work With On-Call Safety Patrol

Construction on the Central 70 Project will ramp up this week as work begins along the interstate with a new, month-long closure along a portion of Brighton Boulevard.

Starting Oct. 1, a portion of Brighton Boulevard, between 44th Street and I-70, will be closed for approximately one month. Crews will be installing a drainage box under the roadway, south of the interstate.

  • To navigate this closure, northbound traffic will turn left onto 44th Street and follow it to Brighton Boulevard.

There will also be one northbound lane open to access eastbound I-70.

  • Southbound traffic will turn right onto 46th Avenue and follow the detour to Brighton Boulevard.
  • All on- and off-ramps to and from I-70, in each direction, will remain open.
  • 46th Avenue between Brighton Boulevard and York Street remains closed.

Work will begin this week on eastbound I-70 between Quebec Street and I-225. Throughout the week, sections of concrete barrier will be placed at night to prepare for the first traffic shift.

Travelers can expect traffic-pattern changes as crews shift traffic inward so construction on the new lanes can begin. Emergency pull-off areas will be available every half mile.

A new Central 70 Safety Patrol is in place to help keep traffic moving. This service assists stranded motorists by clearing disabled vehicles from travel lanes, changing flat tires, jump-starting batteries, and helping law enforcement personnel as requested.

Since June 2018, the Central 70 Safety Patrol has responded to nearly 1,300 calls along the corridor. Motorists are not charged for these services. To access safety patrol, motorists dial 511 and sign a waiver when the truck arrives. These propane-powered vehicles will be clearly marked as "Safety Patrol," with the Central 70 Project logo.

CDOT currently has safety patrol vehicles stationed throughout the metro area. By adding these new vehicles dedicated to the Central 70 Project, the existing fleet can be redistributed to better serve the metro area.
