Construction Update

Upcoming Activities:

The week of July 27, crews are scheduled to start milling and paving work along northbound I-25 below the US 6 bridge to create a cross slope that allows for positive drainage across the highway. This work will involve various overnight lane closures along northbound I-25 near US 6.

Also the week of July 27, there will be an overnight closure of the eastbound US 6 off-ramp to northbound and southbound I-25 so crews can shift the ramp lanes slightly to the inside to take out a curved alignment that has been in place for several months to facilitate construction activities. During the overnight closure of this ramp, eastbound US 6 traffic will be directed to continue east to the Osage Street exit and use westbound US 6 to access either northbound or southbound I-25.

Crews are tentatively scheduled to move traffic onto the new, permanent on-ramp from Federal Boulevard to eastbound US 6 the weekend of July 31. This work will require closing the Federal on-ramp to eastbound US 6 for the weekend. After this occurs, construction crews will be able to build the collector-distributor lane between Federal Boulevard and Bryant Street.

Ongoing Impacts:

Commuters are advised to use caution and drive carefully through the new traffic alignment on US 6. Lanes have been narrowed slightly and the posted speed limit reduced to 45 mph.

Ongoing traffic impacts currently in place:

  • The southbound I-25 off-ramp to eastbound US 6 is closed and will reopen in summer 2015.
  • The Lowell on-ramp to eastbound US 6 will remain closed until Summer 2015.
  • The Bryant Street on and off-ramps are also closed for about one year for construction of the collector-distributor roads on both sides of US 6.
  • The Osage Street on-ramp to westbound US 6 is closed while crews continue reconstruction of the US 6 bridges over I-25 and the BNSF railroad tracks. To detour around this closure, motorists should take Osage Street to 3rd Avenue, 3rd Avenue to Santa Fe Drive, Santa Fe Drive to 8th Avenue, 8th Avenue to Kalamath Street, and Kalamath Street south to access westbound US 6.
  • All lanes on Federal Boulevard have been narrowed and southbound Federal is reduced to two lanes as efforts are under way to rebuild this bridge over US 6.

Explore Commuting Options

If you find it too stressful to drive through the US 6 corridor while it is under construction, you might want to explore alternative modes of transportation. This could include using the Regional Transportation District’s West Rail Line or bus services. Click here for information on RTD’s light rail service.
