March 15, 2025 – April 15, 2025, Completed Work: The contractor has completed demolition of the west portion of the bridge deck and removed old piles. The contractor has also completed the sheet piling around the abutment # 1 area and completed sediment and erosion control protection. This allowed for completion of bent #2 test and bearing piles. 

Anticipated work April 15, 2025 – May 15, 2025: The contractor intends to form and pour the bent #2 concrete piles cap which would support the bridge beams. They also intend to remove the center portion of the existing bridge and old piles to be able to drive the bent #3 piles. Bridge demolition will keep S.D. Highway 10 completely closed to traffic.
