Major bridge replacement projects in urban corridors often require contractors to balance transportation improvements, environmental stewardship, and community impacts. In Denver, the reconstruction of the I-25 and Alameda interchange has been recognized for its delivery approach and project outcomes.
Ames Construction has received a 2026 Infrastructure Construction Excellence Award from the Colorado Contractors Association for its work on the I-25 and Alameda Bridge Replacement over the South Platte River in the Highway/Transportation Bridges and Structures category.
The project involved replacing the oldest bridge in Colorado's state highway network while reconstructing nearby intersections and reconfiguring the I-25 and South Santa Fe Drive interchange.
In addition to roadway improvements, the project expanded multimodal transportation options through the construction of new trails, sidewalks, and an on-street cycle track that connects to the regional trail system.
The work was performed in one of Denver's busiest transportation corridors adjacent to the South Platte River, requiring careful coordination to maintain traffic flow and minimize disruptions to surrounding neighborhoods and businesses.
According to project information released by Ames Construction, the bridge and interchange improvements were completed on time and within budget. The project also recorded no safety incidents and no environmental violations during construction.
Urban transportation projects increasingly place emphasis on safety performance, environmental compliance, and maintaining access for motorists, cyclists, and pedestrians during construction activities. These measures have become important benchmarks in evaluating project delivery across state transportation programs.
For transportation owners and contractors, the I-25 and Alameda Bridge Replacement demonstrates the growing complexity of bridge reconstruction projects that incorporate multimodal infrastructure and environmental considerations alongside traditional roadway improvements. The project also highlights the importance of schedule performance, community coordination, and safety outcomes in delivering major infrastructure improvements within active urban corridors.
