Arapahoe Bridge over Big Dry Creek Replacement Project

Reconstruction of the bridge on Arapahoe Road, east of University Boulevard is underway. The existing bridge over Big Dry Creek was originally constructed in 1945 and is past its useful life. The Arapahoe Road Bridge project will replace the existing bridge with a wider and taller structure, improve pedestrian access over and around the bridge, and make improvements to the Big Dry Creek waterway. Construction is expected to take 18 months to complete.


Project Update (September 2022)

Despite work delays caused by heavy rains in the project area, the project is currently still on schedule and within budget. Work hours are from 7 a.m. to 6 p.m., Monday through Friday. One lane of traffic will be maintained in each direction during construction. 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.

Road closures should be 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. To stay informed, sign up for our project announcements here, or follow us on social media @CentennialGov.

Upcoming Construction Impacts:

  • Next three weeks – Crews will backfill existing concrete abutments and setting bridge girders overnight. After the bridge girders are set, work will begin on the bridge deck. Additionally crews will continue installing the new storm sewer.
  • Remainder of September – Work on the new bridge deck will extend through the end of the month. Additionally, crews will close Elizabeth Street at Arapahoe Road to install the new storm sewer. Watch for specific updates from our team regarding these closures and related detours later this month, as the work was delayed from July.
  • Ongoing – Traffic continues to travel in new lane configurations to accommodate construction. One lane will be provided in each direction throughout the duration of this construction phase – ending fall 2022.

 Detour routes on University Boulevard and Dry Creek Road are highly encouraged.

The pedestrian/bike path is closed for the duration of the project. VIEW THE DETOUR MAP
