The Mississippi Department of Transportation has plans to repair and improve the five bridges on Interstate 20 in Vicksburg.
According to information from the Mississippi Department of Transportation, the bridgework is expected to begin when the South Frontage Road extension project is completed, sometime in spring 2023.
MDOT spokesman Mike Flood said a starting date for the bridge project has not been set.
The bridges designated for work are 4.5A, which crosses Old Highway 27; 4.8A and 4.8 B, which cross Clay Street; and 4.9A and 4.9 B, which cross Old U.S. 80.
The project includes removing and replacing existing bridge rails, end posts and a portion of the bridge deck on all the bridges; installing new guardrails; removing and replacing all existing bridge joints where the bridge spans join together; and installing pressure relief joints at all bridge ends.
Pressure relief joints allow the bridges to expand and contract as temperatures change.
Additional work planned for bridge 4.5A at Old Highway 27 includes pressure washing and cleaning all debris from the existing caps and bearings, removing the pile encasement wall section to repair piles, installing pile repair plates to repair broken pilings and connecting angles.
Also, all exposed steel pilings, connecting angles and the repair area will be painted, new pile encasements —concrete sleeves to protect and reinforce the bridge pilings — will be formed and poured, and the existing exposed steel of the superstructure and bearings will be painted.
