High Line Canal Trail: Colfax to I-70

Construction Project Overview

The city of Aurora, in collaboration with American Civil Constructors, started work the week of Jan. 30 on a multi-use trail to close the gap along the High Line Canal between Colfax Avenue and recent improvements constructed north of I-70. 

The High Line Canal Trail construction project, which spans nearly two miles, will include:

  • A continuous 8-foot-wide concrete trail
  • Two pedestrian bridges (one to cross over the canal just south of Smith Road and one over
  • I-70 just east of the Tower Road exchange)
  • An upgraded railroad crossing to promote pedestrian and cyclist safety
  • Access to the 71-mile High Line Canal Regional Trail within the metro area

Designed with community input, the new trail will provide close-to-home, accessible recreation opportunities within the community and serve a diverse population that may otherwise have limited opportunities to access natural areas.

The city has been granted federal funds through the Denver Regional Council of Governments to help pay for the trail construction with city capital improvement funding used as a match amount. Additional funding partners consist of the Conservation Trust Fund, Adams County Open Space Grant, and the Adams County Open Space Tax Shareback.

Construction Updates

American Civil Constructors will begin work on the project's south end and between East Colfax and East 19th avenues on the east side of Tower Road and along the canal.

Vehicular and pedestrian travelers can expect intermittent delays in these areas for the first two months. Alternate routes are recommended when possible. The contractor also has started working on the bridge abutment just south of I-70 when the project.

Work This Week

  • Backfill and excavate exterior of MSE wall
  • Intersection push button completion of available completed intersections
  • A & B coping and trail formwork
  • Pour and cure coping/moment slab work

Traffic Alert

From Sept. 13 to Oct. 13, an around-the-clock detour will be in place for truck traffic needing to access businesses off 28th Avenue between Tower Road and Airport Boulevard.

The detour is necessary to permit construction crews to complete concrete pavement and sidewalk improvement work on the west side of the Tower Road and 28th Avenue intersection, which will prevent truck traffic from getting through.
