View Original Plans For This Historic Bridge and A Planned Alternate Design

This bridge is a rare surviving example of a cantilever through truss bridge in Arkansas. It is one of two similar bridges remaining on the White River, and yet both are to be demolished showing a complete disregard by the Arkansas State Highway and Transportation Department (ASHTD) to preserve this critical part of the state's transportation. Instead it will be destroyed forever. These White River Bridges are significant on a national scale as late examples of bridges designed by noted engineer Ira G. Hedrick. Hedrick was in the early 20th century briefly associated with famous engineer J.A.L. Waddell. This bridge shows work done by Hedrick on his own. Of particular interest is Hedrick's design for the suspended span. Large empty holes are visible on the suspended span end posts. These would have been used during erection of the bridge to move the suspended span into place. Also of interest are large expansion joints on the bottom chord at the end of the suspended span. This is an unusual design detail not found on similar bridges designed by other engineers.

This bridge's significance is further enhanced by the fact that it enjoys outstanding historic integrity with no major alterations. Unaltered cantilever truss bridges of this size are rare nationwide.
