CO 88/Belleview Avenue Traffic Safety Project

About the Project:

In early October, the Colorado Department of Transportation began the Belleview Avenue (CO 88) Traffic Safety project between Federal Boulevard and South Prince Street. This traffic safety project will install raised medians along Belleview Ave, as well as signal replacement, curb ramp upgrades, curb and gutter replacement, erosion control, signage, striping, and drainage modifications. Work will occur in both the eastbound and westbound lanes of the highway, as well as along the sidewalks within the project zone.

Project Benefits

  • Installation of raised medians to improve traffic safety along this highly frequented stretch of Belleview Avenue
  • New traffic light signals for clear motorist and pedestrian direction
  • Upgrades to curb ramps to meet ADA standards and other added safety elements and improvements such as curb and gutter replacement, erosion control, signage, striping, and drainage modifications

Work Schedule:

  • The project will take place between mile point (MP) 7.94 to MP 8.22 and is expected to be substantially completed in December 2023, with final seeding and erosion control to occur in April and May 2024.
  • The majority of work will occur during daytime working hours Monday through Friday between 7 a.m. and 5 p.m. with lane closures between 9 a.m. and 3 p.m.
  • In mid-November, there will be approximately two to three nights of overnight work between 6 p.m. and 6 a.m.
  • Winter shutdown January 26-March 31

Traffic Impacts:

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

  • Eastbound and westbound single lane closures during normal working hours. Closures will begin in the eastbound lanes and then switch to the westbound lanes. In mid-October, there will be approximately one week of closures in both directions. 
  • The left turn lane from westbound Belleview Ave onto southbound Prince St will be closed through October with a concrete barrier. Motorists should follow the posted detour signage to access Prince St while the closure is in place: left on Federal Blvd, left on W Progress Ave, left on W Centennial Dr.
