Interstate 25 and U.S. Highway 50B Interchange Project

under construction

The project involves replacing three structurally deficient and functionally obsolete bridge structures with five new bridge structures, including two over I-25, two over the Union Pacific Railroad, and one over Fountain Creek. It also includes retaining and noise walls, roadway and ramp reconstruction, embankment, safety improvements, drainage, and erosion control. The interchange will be relocated just north of the current interchange and will operate as a diverging diamond interchange to improve drivability and safety.
