Segmental Creates Longest Span in Colorado - 4th Street Bridge, Pueblo, Colorado


The last segment of the 4th Street Bridge (Fig. 9) in Pueblo, Colorado was cast on July 30, 2010, setting a new record for Colorado’s longest highway span at 378'. The twin 1,137' long concrete bridges cross 28 sets of active heavy rail tracks, local roads and the Arkansas River. Concrete segmental balanced cantilever construction allowed the bridge to be built from above as rail operations in the Pueblo Rail Yard continued below.

Aesthetics selected by the community reflect the themes of Contemporary Sculpture, Pueblo Heritage and the Natural Environment. The bridge was designed by FIGG for the Colorado Department of Transportation and is being built by Flatiron. The final traffic configuration is expected to be in place by December 2010.
