Arapahoe Avenue Pedestrian and Bike Bridge Replacement Over South Boulder Creek

Construction is anticipated to begin on Aug. 11, 2026, and last about 2 months, pending weather and contractor availability.

Expect impacts to driving and detours when walking and biking. You can continue to access nearby neighborhoods and businesses during construction. View the Cone Zones map for updates.

When driving, expect:

• Periodic delays and flaggers guiding traffic during daytime lane closures.
• Two separate, full nighttime closures of westbound vehicle lanes near the impacted location during safety-critical work: removing the existing bridge and installing the new bridge. There will be advance notice as construction progresses and dates are determined. Vehicle detours will be via 63rd Street to Valmont Road and Cherryvale Road to Baseline Road.

When walking or biking, travelers can expect:

• The South Boulder Creek Trail underpass beneath the bridge will remain open throughout construction, except during safety-critical operations. Traffic control will assist travelers through the construction zone during these intermittent underpass closures.
• A detour for biking and walking along Arapahoe Avenue to Cherryvale Road.

When taking the bus, riders can expect:

• Bus Stop 12231 at Arapahoe Avenue & Cherryvale Road (WB) will be closed. Take the bus at nearby Stop 12243 at Arapahoe Avenue & Old Tale Road.

Funding comes from the Multi-Use Path Maintenance Program as part of the city’s Capital Improvements Program.
