Abstract:

Standards for Single Span Prefabricated Bridges were developed by HDR for the Iowa Department of Transportation in 2016 for the use on the county road system. These standards incorporated single span precast or precast/pretensioned concrete box beams with span lengths ranging from 30-feet to 70-feet, clear roadway widths of 24-feet and 30-feet, and skews of 0o, 150 or 30o. Additionally, the standards provided both cast-in-place and precast abutment design options founded on steel H-piles. The abutment designs allowed for either steel sheet pile or concrete wing walls for the 0o skew bridges, with concrete wingwalls only for abutments at a 15o or 30o skew. The standards were developed utilizing the MicroStation V8i CADD software.
