Fourth Street Bridge, Pueblo, Colorado

SEGMENTS, FALL 2009, VOL. 54

The Colorado Department of Transportation’s new Fourth Street Bridge in Pueblo, Colorado is taking shape. Construction of the twin 1,137' long concrete bridges began on October 17, 2007 and is proceeding on schedule. Three of the four end spans and the majority of substructure work have been completed. In addition, the first cantilever was completed in June 2009. Cantilevers now extend over the 28 sets of active heavy rail tracks in the Pueblo Rail Yard, as well as the Arkansas River.

Concrete segmental balanced cantilever construction (Figs. 6 and 7) allows railroad operations and recreational use of the river to continue below. Slender piers create a minimal footprint and feature aesthetic features selected by the community. The new bridge will also include two lanes of traffic in each direction, with wide safety shoulders and a multi-use path, to provide a high-quality and sustainable solution for the community.
