Arapahoe Road bridge reconstruction: Traffic switch starting April 14

Reconstruction of the bridge on Arapahoe Road, east of University Boulevard is underway. Road closures are expected during the project. Work hours are 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. 

All construction activities are weather-dependent and subject to change for the safety of crews and the traveling public.

Upcoming Construction Impacts

Starting April 14 traffic will be shifted to a new lane configuration to accommodate the next phase of construction. One lane will be provided in each direction for the duration of the next phase which will continue bridge demolition and begin construction of the new bridge. Restricting traffic to one lane in each direction will provide additional room for construction activity and an additional buffer between the traveling public and construction equipment, increasing safety for crews and commuters alike.

This phase of construction is expected to last through August, 2022.

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.
