E. 96th Avenue Widening Project
About the Project
The E. 96th Avenue widening project between Chambers Road and Tower Road presents an exciting opportunity to improve connectivity and infrastructure along this important arterial roadway.
Before 2015, E. 96th Avenue did not extend across Second Creek, instead turning south into Buckley Road. That changed in 2015 when the city completed construction of the bridge over Second Creek and the two westbound lanes. With additional new development continuing to occur in the area, the current project is set to complete the full buildout of this essential roadway to four lanes with a dividing median from Tower to Chambers.
Project Details
This project will construct the median and two eastbound lanes from Chambers Road to Tower Road and includes sidewalks, multi-use paths, storm sewer, water lines, traffic signals at Chambers, Landmark, Reunion/Telluride, modifications to the signal at Tower Road, and completion of the bridge over Second Creek.
Current Status and Impacts
Project dates may be adjusted due to weather, material availability, contractor scheduling, or unforeseen conditions. Updates will be provided as the project progresses.
Safety Warning to the public and residents
For the safety of residents and workers, the public should not enter active construction zones along E. 96th Avenue and Buckley Road. While some newly paved areas may appear safe for walking, running or bicycling, they remain active work zones with ongoing construction activity and heavy equipment.
Buckley Road is closed and is being used by the contractor to transport equipment and materials between E. 88th Avenue and E. 96th Avenue. Pedestrians and cyclists should avoid this area.
The Wildlife Refuge Perimeter Trail remains open, except along E. 96th Avenue between Chambers Road and the Second Creek Bridge. A signed detour is available through the refuge for pedestrians and bicyclists. The Second Creek pedestrian underpass through CALU Park also remains open and is the preferred route for crossing E. 96th Avenue. We appreciate the community’s patience as work continues to improve E. 96th Avenue.
Road & Lane Closures
- A temporary traffic signal is now in place at the Landmark Drive intersection and is expected to remain until the next traffic configuration change in mid- to late October. Following the traffic switch, the permanent signal at Landmark Drive will be activated. The next configuration will have one lane in each direction, with westbound traffic on the north side of the median and eastbound traffic on the south side.
- Aug. 17 – Nov. 6: The intersections at Mobile Street and Kalispell Street will be closed at E. 96th Avenue. A signed detour will direct motorists around the closures while the South Adams County Water and Sanitation District completes water main improvements and crews continue roadway construction.
- Sep. 21 – Oct. 9: There will be intermittent daily lane closures on E. 96th Avenue during the hours of 9 a.m. to 3:30 p.m. One lane will be closed, and traffic will be stop-controlled with one-way traffic. This will be for the work required for the Laredo Street traffic signal work. There will be a total of six (6) days of lane closures over the three (3) week period.
Construction Progress
- Traffic has been switched to the newly constructed road on the south side of the median. Motorists are asked to be extra cautious when using E. 96th Avenue, as much has changed. During this phase of construction, crews will be working on completing the north side of the roadway, including the Second Creek Bridge deck, pedestrian underpass, irrigation system improvements, curb and gutter, sidewalk, and median construction.
- South Adams County Water & Sanitation's water main work on Laredo Street from E. 98th Ave to E. 99th Ave is now complete and Laredo Street is back open to traffic.
- Work has started on the Laredo Traffic signal and the northern portion of the pedestrian underpass at Reunion Pkwy. Work continues on the construction of the traffic signals at Landmark Drive and Telluride Street, raised medians, street lighting, and irrigation. Final landscaping will begin after the irrigation system is installed.
- The future eastbound lanes from the west end of the project to just past Second Creek Plaza Drive have been paved. The utilities at Tower Road have been relocated, allowing the contractor to complete the paving of the south side of E. 96th Avenue at Tower Road. Once this paving at Tower Road is complete, the contractor will switch traffic into the Phase II configuration and start the construction on the north side of E. 96th Avenue.
- The underpass at 2nd Creek is now open. With the Chambers Road intersection being closed, there is no other safe crossing of E. 96th Avenue West of Telluride Street. Bicyclists and Pedestrians using the Wildlife Refuge perimeter path should access the path via the underpass at the Second Creek Bridge and CALU Park.

Arsenal Perimeter Trail detour
As of mid-April 2025, a detour is currently in place at the northeast corner of the Arsenal Perimeter Trail, near where E. 96th Avenue formerly intersected with Buckley Road. The detour carries users onto the Rocky Mountain Arsenal National Wildlife Refuge, cutting across the northeast corner of the arsenal property between Chambers Road at 96th and Buckley Road north of E. 88th Avenue. The pedestrian underpass at the Second Creek Bridge is back open providing a safe crossing of E. 96th Ave for pedestrians and bicyclists. The pedestrian underpass can be accessed from the south side of E. 96th Ave via CALU Park, see map. Please note that pets are prohibited on refuge property and will not be allowed on the detour route.
The construction of the Arsenal Perimeter trail is being constructed and is expected to open back up this summer. This will allow the detour through the Wildlife Refuge will be removed.
This map shows the temporary closure and detour of the E. 96th Avenue Arsenal Perimeter Trail in Commerce City. The closed section is highlighted in red, running along E. 96th Avenue from just west of Second Creek to Buckley Road. A green dashed line indicates the detour route through the Rocky Mountain Arsenal National Wildlife Refuge, curving southwest before reconnecting to Buckley Road. The detour is marked with a note: “Trail Detour – No pets / Desvío del sendero – No se admiten mascotas.” Several landmarks are shown, including Sweet Awakening Wellness Center, Buffalo Highlands Fit & Play Park, and residential neighborhoods along E. 96th Avenue.
