Fourth Street Bridge, Pueblo, Colorado

SEGMENTS, SPRING 2010, VOL. 55

Construction continues for the 4th Street Bridge in Pueblo, Colorado. The westbound superstructure was completed in December 2009 and traffic is expected to be moved onto the new structure in the spring. Concrete segmental balanced cantilever construction ( Fig. 11 ) allows the bridge to be built from above as rail operations in the Pueblo Rail Yard continue below.

The twin 1,137' long concrete bridges cross 28 sets of active heavy rail tracks, local roads, and the Arkansas River. When complete ( Fig. 12 ), the main span will hold the record of Colorado’s longest highway span at 378'. 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.
