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.

Construction Update

Upcoming Activities:

US 6 overnight closure coming Saturday, Sept. 13: During the overnight hours onSaturday, Sept. 13, crews will perform critical work to prepare for the installation of a new waterline on the Federal Boulevard bridge over US 6. This work will require a full overnight closure of US 6 under the Federal Boulevard bridge for safety purposes. This closure will occur between the hours of 10 p.m. and 6 a.m., with single lane closures beginning at about 8 p.m­.

  • Westbound US 6 traffic will detour around this closure using the Federal off and on-ramps.
  • Eastbound US 6 traffic will detour at the Federal off-ramp, then use the 5th Avenue on-ramp to connect back with eastbound US 6 toward downtown Denver.

Bridge work near I-25: There will be work each night on I-25 near US 6 with various lane closures as needed over the hours of 8 p.m. and 5 a.m. This work includes cleanup and bridge work on the US 6 bridge over I-25 and the new northbound I-25 off-ramp to westbound US 6 following the significant work performed this weekend in conjunction with the I-25 Gap Lane Project.

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:

  • Temporary closure of the westbound US 6 off-ramp to Lowell/Perry: The westbound US 6 off-ramp to Lowell/Perry is temporarily closed for approximately three months. Click here for more information.
  • 5th and Decatur drainage line installation: Daily, during the hours of 7 a.m. to 5 p.m., commuters should be on the lookout for various lane closures in either direction on 5th Avenue for continued drainage line installation.
  • The Lowell on-ramp to eastbound US 6 will remain closed until fall 2014.
  • 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 until early 2015 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.
