Arapahoe Road bridge reconstruction

August 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. The construction team expects traffic impacts to extend into October.

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 Impact

Week of Aug. 14
Crews will prepare and pour a retaining wall.

Remainder of August
Crews will continue ongoing stream stabilization and utility relocation work in partnership with Denver Water.

Traffic continues to travel in new lane configurations to accommodate construction. One lane will be provided westbound, and two lanes will be provided eastbound (with occasional lane closures during construction hours) through the duration of the next construction phase. 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 are expected 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.
