Weekend closure of US 6 ramps to I-25 precursor to new alignment

October 9, 2015 - Denver Metro/CDOT Region 1 - Eastbound US 6 traffic moves into final configuration Monday morning.

DENVER – The eastbound US 6 off-ramp to northbound and southbound I-25 will close this weekend to facilitate shifting eastbound US 6 traffic into its final alignment.

The eastbound ramps in the Federal interchange have been closed all week and this weekend marks the final push of grading, paving, barrier and lane striping work to put eastbound US 6 traffic into its final alignment Monday morning.

The eastbound US 6 off-ramp to I-25 will close at 10 p.m. Friday, Oct. 9, and reopen Monday, Oct. 12, at 5 a.m. This Sunday night there will also be overnight closures of the southbound and northbound I-25 off-ramps to eastbound US 6 and lane closures along eastbound US 6 starting at 7 p.m. to facilitate this work.

When all lanes and ramps open Monday morning, eastbound US 6 drivers will notice several changes (see graphic on next page). The most notable change is that eastbound drivers wanting to access I-25 will need to be prepared to exit sooner as drivers will now access the I-25 ramps via a collector-distributor lane that starts near Federal Boulevard. This is several hundred feet west of where drivers are accustomed to exiting to I-25.


  • Eastbound US 6 to northbound and southbound I-25: Drivers can enter I-25 at either Colfax or Alameda Avenues or continue east on US 6 to Osage and exit there to get onto westbound US 6 to reach the ramps to I-25.

PROJECT INFORMATION: The $98 million US 6 Bridges Design-Build Project will replace six obsolete bridges on US 6 between Knox Court and I-25, improve traffic movements in the I-25 and US 6 interchange and enhance driver safety by eliminating several traffic weave movements along US 6 between Federal Boulevard and I-25. Kraemer North America, the primary contractor, is on schedule to complete the project in late October – 20 months after initial construction impacts and nearly one year ahead of CDOT’s originally estimated timeframe for the project.
