SHREVEPORT, LA — The Louisiana Department of Transportation and Development (DOTD) announces that the Spring Street Bridge (LA 1 northbound) repair project from I-20 into downtown Shreveport continues to move forward. The contractor will soon begin installing piles for the repairs to the overpass. The 83-year-old structure was significantly damaged during a train derailment that occurred on Friday, April 24, 2020.

So far, the contractor, CEC, Inc., has installed the temporary span steel support to lift the bridge deck and hold it in place to allow repairs to be conducted underneath.

The columns and bracing steel of the bent have been removed, and an 18” culvert has been installed next to the damaged bent to provide a flat working surface. A ditch has also been relocated to maintain proper drainage while work is underway.

Sheet piles have been installed, which create a cofferdam and shore-up the area for the new spread footing. The sheet pile holds back the soil and additional forces from the nearby train tracks. Excavation has begun in the cofferdam in order to remove the existing footing of the damaged bent.

Soon, the contractor will begin installing the helical piles, which can be placed more quickly than conventional piles, and are favorable when working in limited access conditions, such as directly adjacent to busy railroad tracks. Additionally, helical pile installation is a vibration-free process, reducing the noise level and potential vibration for nearby buildings in a downtown area.

DOTD continues to work closely with both Kansas City Southern and Union Pacific Railroads, as well as navigate the necessary bridge repairs between frequent train traffic that requires crews to temporarily vacate the project site.

The Spring Street overpass serves as the primary route into the downtown Shreveport area from I-20. Until repairs are complete, the bridge and off-ramp from I-20 (Exit 19A) to Crockett Street will remain closed.
