Construction Update

Upcoming Activities:

  • Southbound I-25 off-ramp to westbound US 6: Crews will close this ramp from 10 p.m. to 5 a.m. for guardrail repair. To detour, motorists should take Colfax Avenue, Alameda Avenue or 8th Avenue west to Federal Boulevard, then use the Federal on-ramp to westbound US 6.

  • Eastbound US 6 on-ramp to southbound I-25: This ramp will close from 10 p.m. to 5 a.m. for repairs to the array of barrels used to keep drivers safe through the construction zone. To detour around this closure, motorists should take the US 6 off-ramp to Osage Street, then use Osage to loop back and access the on-ramp to SB I-25. 

  • Eastbound US 6 off-ramp to Federal Boulevard: This ramp will also close from 10 p.m. to 5 a.m. for barrel array repairs near the Federal Boulevard bridge over US 6. This work will include various overnight lane closures on US 6 as needed. To detour around this closure, motorists are encouraged to exit eastbound US 6 at Sheridan Boulevard and use Alameda Avenue or Colfax Avenue to go east to Federal Boulevard.

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 South Platte River trail is closed between 7th Avenue and Bayaud Street and will reopen in spring 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.
