Wax Lake Bridge Construction Photographs 1940-1941
Collection — Box: PHOTO 0009.01
Identifier: SC Photo-0009
Abstract
A collection of construction photographs of a steel railroad bridge erected on a dry flat plain which eventually became a Mississippi River floodway channel. The channel beneath the bridge elements was dredged after the bridge was constructed. This construction procedure was in reverse of the usual building process. Construction by Bethlehem Steel began in late 1940 and completed in early 1941. The reverse building process was unusual at the time. The bridge is also known as the Wax Lake...
