Bridge #322
Vigo County’s bridge 322 was built in 1965 on 13th Street as a 132’ long, two-span adjacent prestressed concrete beam bridge with a 62-degree skew over Lost Creek. It was identified as a Non-Select historic bridge because of its significant skew. HWC’s innovative approach during the Historic Bridge Alternatives Analysis (HBAA) found that replacing the superstructure with steel beams was the most feasible and prudent alternative (B2). All alternatives were investigated for the HBAA as the change from a concrete to steel superstructure was viewed as demolition by the historic consulting parties. The bridge was marketed for reuse in accordance to INDOT standards. A scour analysis, foundation repairs, drainage design, intersection design, and utility coordination were included in the project.
