US 6 Paving Wednesday Night Precedes Busy Weekend of Work

September 24, 2014 - Denver Metro Colorado/CDOT Region 1 - DENVER – Overnight on Wednesday, Sept. 24, crews will begin paving portions of the new westbound US 6 roadway between Federal Boulevard and Knox Court as part of the Colorado Department of Transportation’s (CDOT) ongoing US 6 Bridges Design Build Project.

This work will require various lane closures in each direction on US 6, as well as a full closure of the Federal Boulevard on-ramp to westbound US 6.

This work will occur between the hours of 8 p.m. and 5:30 a.m.

“Paving on Wednesday night is just a sneak peek of things to come,” said Kevin Sullivan, CDOT Project Director. “It’s going to be a busy weekend of work but we will do everything we can to minimize impacts to the traveling public, especially for those participating in the 2014 Komen Colorado Race for the Cure in Denver.”

Project work this weekend will include continued concrete paving on westbound US 6, in addition to girder placement on the north half of the new US 6 bridge over I-25.

Concrete paving on westbound US 6 will require closing the right lane of westbound US 6 between Federal Boulevard and Knox Court.

  • This work will occur between the hours of 8 p.m. on Saturday, Sept. 27, and5:30 a.m. Monday, Sept. 29.
  • The Federal Boulevard on-ramp to westbound US 6 will close in conjunction with this work.

Setting the girders for the US 6 bridge over I-25 will involve the following traffic impacts:

  • Saturday, Sept. 27, 10 p.m. to 5 a.m.
    • Full closure of northbound I-25
    • Triple lane closures on southbound I-25
  • Sunday, Sept. 28, 10 p.m. to 5 a.m.
    • Full closure of southbound I-25
    • Triple lane closures on northbound I-25
  • NOTE: Lane closures will begin at about 8 p.m. each night.

Sullivan added, “We do expect some traffic delays during the day on Sunday, so we encourage drivers to plan their drive accordingly and consider using alternative transportation methods such as RTD’s Light Rail service.”


  • To access westbound US 6 from Federal Boulevard, drivers should take Alameda Avenue or Colfax Avenue west to Sheridan Boulevard, and take Sheridan Boulevard to US 6.
  • Northbound I-25 detour: Motorists will detour off I-25 onto eastbound US 6, exit eastbound US 6 at Osage Street, and take Osage Street to access the on-ramp to northbound I-25.

  • Southbound I-25 detour: Motorists will detour west on US 6 to Federal Boulevard, south on Federal Boulevard to 5th Avenue to merge onto eastbound US 6, and east on US 6 to reconnect with southbound I-25. There could also be delays along eastbound US 6 near I-25 with additional traffic following this detour route.   

PROJECT INFORMATION: The $98 million US 6 Bridges Design-Build Project will replace six obsolete bridges on US 6 between Knox Court and I-25, improve traffic movements in the I-25 and US 6 interchange and enhance driver safety by eliminating several traffic weave movements along US 6 between Federal Boulevard and I-25. Substantial project completion is planned for August 2015.
