 Well Road Bridge Replacement

View Next Project >>

The Well Road bridge over I-20 was an aging bridge in need of replacement. Only four days were provided to replace the entire bridge because of the significant amount of traffic on I-20. This required constructing a new bridge on an adjacent temporary structure and moving the old bridge out while concurrently moving the new bridge in span by span. Self-propelled modular transporters (SPMT) were used for the movement process. NDM provided engineering services for the design and layout of the temporary structure as well as analysis of the new structure while the spans were being moved by the SPMTs. Constant monitoring of the bridge on the temporary structure was required as well as monitoring of the spans for excessive twist and rotation during transport on the SPMTs.
