Arapahoe Road bridge reconstruction

October 2023 Project Update

After discovering a utility conflict with the proposed bridge, the team has been working closely with Denver Water to relocate a waterline to accommodate the bridge work and improve an aging piece of Denver Water’s infrastructure.

Work hours are 7 a.m. to 6 p.m., Monday through Friday. Please pay attention while driving in the work zone and never drive distracted. Motorists should expect increased Arapahoe County Sheriff patrols in neighborhoods north and south of Arapahoe Road to manage cut-through traffic. All construction activities are weather dependent and subject to change for the safety of crews and the traveling public.

Upcoming Construction Impacts

Ongoing through October – Through October, crews will continue to build the roadway over Big Dry Creek. Crews are completing finishing activities for the bridge, including stone and wall aesthetic work. Under the bridge, crews continue stream stabilization efforts and will install new waterline infrastructure. In addition to the work above, crews will prepare and pave the North Trail through the construction zone.

Ongoing – Traffic continues to travel in new lane configurations. To support final roadway construction and paving, rolling lane closures are anticipated. Tentatively starting 10/18, traffic will be restricted to one lane in each direction, and the phase is anticipated to last two weeks. Closures at Elizabeth are also anticipated with duration still to be determined. Detour routes on University Boulevard and Dry Creek Road are highly encouraged.

Project Summary

The existing bridge over Big Dry Creek was built in 1945 and is past its useful life. This reconstruction project will:

  • Replace the existing bridge with a wider and taller structure
  • Improve pedestrian access over and around the bridge
  • Make improvements to the Big Dry Creek drainage and waterway system

Road closures will continue during the project. Prior to any closures an announcement will be sent to advise the public of alternate travel routes. People living in the nearby neighborhoods will still be able to get to their homes.
