Hampden/Colorado Underpass Project

High Line Canal Trail New Alignment

Upcoming Closures of Hampden Avenue 

With installation of the Colorado Boulevard underpass complete, crews will now begin work on the Hampden Avenue underpass, which will require Hampden to fully close at Colorado Boulevard for two weekends. Installing the underpass over two weekends will allow crews to complete the work more quickly and prevent multiple street closures during the week. Below is the schedule (weather permitting):

  • Friday, July 31, beginning at 7 p.m. to Monday, August 3, ending at 5:30 a.m., a FULL CLOSURE of eastbound and westbound Hampden Avenue, near the Colorado Boulevard intersection
  • Friday, August 7, beginning at 7 p.m. to Monday, August 10 ending at 5:30 a.m., a FULL CLOSURE of eastbound and westbound Hampden Avenue, near the Colorado Boulevard intersection

Detours will be in place while work is underway (see map below). Local traffic will still be able to access Devonshire and Covington neighborhoods. Since the High Line Canal Trail is part of a regional trail system, detours will also be in place throughout the project for those walking and riding bikes. The public’s patience and cooperation during construction are greatly appreciated. All work is weather dependent and subject to change.

Project Information

Beginning the week of May 4, weather permitting, Denver’s Department of Transportation and Infrastructure (DOTI) will start work to create a safer, more convenient connection for people who walk and ride bikes on the High Line Canal Trail. Currently, the trail leaves pedestrians and people on bikes at the intersection of Colorado Boulevard and Hampden Avenue, a busy intersection that can be intimidating to cross on foot or on a bike. This project will build two underpasses to reroute the trail under Colorado and Hampden. The new underpasses will provide a safer experience in alignment with Denver’s Vision Zero efforts to provide safer streets for all.

In addition, between the two underpasses, DOTI will also add a new, 10-foot wide multi-use trail along the north side of Hampden that will also give people more space to bike and walk. The City of Cherry Hills Village will install a new footbridge across the canal at the current dead-end of the High Line Canal trail immediately south of Hampden Avenue, and additional trail parallel to Hampden Avenue to connect the footbridge to the underpass.
