Abstract:The completed high-performance concrete (HPC) bridge on Interstate 25 over Yale Avenue in Denver, Colorado replaced a four-span cast-in-place T-girder bridge. The HPC bridge is a two-span structure using box beams made continuous over the center support. The two spans are 34.5 m (113.3 ft) and 30 m (98.6 ft) long, respectively. The 42-m-wide (138-ft-wide) bridge improved clearances over Yale Avenue without a significant change in the grade of I-25. The initial cost savings are the elimination of two column/pier lines. It is expected that the more durable concrete will provide increased resistance to traffic wear, environmental factors, and the effects of deicing chemicals.
