Construction Update

Upcoming Activities:

Initial Gap Project work: Beginning Monday, July 7, there will be work each night, Monday through Thursday, on I-25 between Alameda Avenue and the US 6 interchange to prepare the roadway for the upcoming I-25 Gap Lane Project. Nightly work will continue for approximately the next month in preparation of a full weekend closure of I-25 in early August. This work will require nightly lane closures as needed on I-25 between the hours of 8 p.m. and 5 a.m.

US 6 roadway re-striping: Each night, watch for various lane closures as needed on eastbound US 6 near Federal Boulevard while crews re-stripe the roadway in preparation for an upcoming traffic shift. Work will occur at night between the hours of 7 p.m. and 5:30 a.m.

The traffic shift will occur later in the summer and will include moving all six lanes of US 6 traffic to the eastbound (south) side of the highway. This will result in temporary closures of the westbound US 6 off-ramp to Lowell/Perry as needed, scheduled to last through fall 2014.

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:

  • 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 is closed for approximately six months and there will be a temporary, six month closure of the westbound US 6 off-ramp to Lowell/Perry coming up in mid-June. More information to follow.
  • 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 northbound I-25 off-ramp to eastbound US 6 is closed for approximately six months while crews reconstruct the ramp and bridge over the BNSF railroad tracks. To detour around this closure, northbound I-25 motorists should exit at 8th Avenue and go east to Kalamath, then go south on Kalamath to 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.
