National Steel Bridge Alliance
HDR Pricing Study
Southeast: Kentucky, North Carolina, South Carolina
Concrete bridges have traditionally dominated the market in this region. In fact, 72% of the bridges studied in this region were concrete I-beam bridges, with only 22 steel bridges of any type (roughly 13%) included in the study.
This limited and skewed dataset makes it diffucult to make a true comparison for this region. Since Illinois and Arkansas border the Southeast region, consider the Central region as an additional data approximation.
A few notes about the Southeast region results:
- Even though steel plate girder bridges are used for more expensive bridges with longer spans, complex bridges, and structures with clearance issues, costs still show them to be competitive.
- Although rolled steel bridges are the most cost-competitive type for bridges with spans less than 140 ft, there is only one such bridge represented in this region's dataset.
