Construction Update

Upcoming Activities:

Weekend closure of northbound I-25 ramps to US 6
Beginning at 10 p.m. on Friday, June 12, crews will close the northbound I-25 off-ramp to the US 6 interchange to allow completion of a new bridge that spans the railroad tracks. The ramps will remain closed all weekend and will reopen by 5 a.m. Monday, June 15. Once this bridge opens Monday morning, drivers entering northbound I-25 from the Santa Fe Drive/Cedar Avenue on-ramp will no longer be forced to merge left, meaning the lane will be continuous all the way to the US 6 interchange. This should improve the flow of traffic on northbound I-25 through the area. Click here for a map showing the location of this lane and the new bridge opening Monday morning.

Detour Routes:

      • Northbound I-25 to westbound US 6: Drivers should take 8th Avenue west to Federal Boulevard, then use the Federal Boulevard on-ramp to westbound US 6.
      • Northbound I-25 to eastbound US 6: Drivers should exit at 8th Avenue and go east to Kalamath Street, then south on Kalamath to access eastbound 6th Avenue

Pedestrian Bridge deck pour: Beginning at 10 p.m. on Monday, June 15, crews will implement a full closure of both directions of US 6 to begin pouring the deck on the new pedestrian bridge connecting Barnum North and South parks. Westbound US 6 will close at Federal Boulevard and eastbound US 6 will close at Sheridan Boulevard. To detour around the full closure of the highway, local traffic can use Alameda Avenue or Colfax Avenue while regional traffic should use I-70, US 285 and C-470. 

Eastbound US 6 traffic shift: Overnight on Thursday, June 18, crews will shift eastbound US 6 traffic to the north between Federal Boulevard and Knox Court. This work will require various lane closures on eastbound US 6 from 7 p.m. to 5:30 a.m.

Southbound I-25 paving operations: Each night next week, crews will implement various lane closures on southbound I-25 as needed for paving operations. Those nightly lane closures will occur from 8 p.m. to 5:30 a.m. each night.

Overnight closures on 5th Avenue: There will also be night work on 5th Avenue for paving operations Sunday, June 14, and Monday, June 15. This will reduce 5th Avenue to a single lane from 9 p.m. to 6 a.m.Sunday night, and close 5th Avenue altogether from 9 p.m. to 6 a.m. Monday night. To detour around the full closure of 5th Avenue, drivers can use 2nd Avenue or 7th Avenue to get from Federal Boulevard to Bryant Street or from Bryant to Federal.

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. For information on bus fares and schedules, click here.

Exploring carpool or vanpool services is another option you might want to pursue. Click here to access an online trip planner where you can input your starting location and destination address into a database to see if there are existing carpool or vanpool services in your area.

If biking or walking are more your speed for short trips, click here for tips on getting to your destination by foot or bicycle.
