TDOT is currently using Accelerated Bridge Construction (ABC) to repair or replace four bridges along I-240, east of Memphis, in a project known as MemFix 4. The Norfolk Southern Railroad bridge is one of the four bridges included in the $54 million project.
The NSRR bridge is being replaced using bridge slide technology, a first for TDOT and the state of Tennessee. Last summer, a new bridge was constructed on temporary foundations beside the old structure to allow rail movement to continue. With the temporary bridge in place, the old structure was removed and new, permanent foundations were constructed.
During three sets of weekend interstate closures, contract crews will slide the two tracks of the new bridge into the permanent location (one track per weekend) and demolish the temporary foundations (one weekend).
The entire project is expected to be completed in June 2019.
