Four lanes open on Arapahoe bridge over Big Dry Creek

The City of Centennial announce the substantial completion of the Arapahoe Bridge reconstruction over Big Dry Creek. A The final striping on Arapahoe Road has been recently completed, allowing two lanes to be open in each direction just east of University Blvd. The enhanced bridge features wider lanes and a taller structure, significantly improving safety for the traveling public.

While vehicular lanes are now open, construction crews are diligently working on stream stabilization efforts under the bridge to the pedestrian and bike path. In the coming weeks, there will be limited sidewalk access to the south side. Toward the end of the month, pedestrian access will shift to the north, and the southside sidewalk will be temporarily closed to facilitate work on the guardrail and driveways.

The reconstruction project, which commenced in early 2022, aimed to replace the original bridge constructed in 1945. Beyond a wider and taller bridge structure, the completed project will enhance pedestrian access over and around the bridge and upgrade the drainage and waterway system for Big Dry Creek.

Ongoing work hours are from 7 a.m. to 6 p.m., Monday through Friday. Motorists are urged to exercise caution while driving in the work zone and avoid distractions. Increased patrols by the Arapahoe County Sheriff in neighborhoods north and south of Arapahoe Road will manage potential cut-through traffic.

All construction activities are subject to weather conditions and may be adjusted for the safety of both crews and the traveling public. For additional information, please visit

The City expresses gratitude for the public’s patience as we bring this project to completion.
