Project is currently under construction. The new bridge is anticipated to be open for traffic Summer 2023 and total project completion anticipated for Summer 2024.

Phase One – Underwater substructure construction and beginning roadway approach work

Phase Two – Westbound lane construction and signal work

Phase Three – Eastbound lane construction

Phase Four – Demolition of old bridge and construction of Pierre and Fort Pierre Plaza’s

A historic bridge project is coming to the Pierre-Fort Pierre area. While the John C. Waldron Memorial Bridge still stands, it’s critical that the structure be replaced. The bridge was opened in the 1960s and is showing signs of deterioration, which can cause a variety of issues. The current structure carries U.S. Highways 14 and 83, along with S.D. Highway 34. The structure is a crossing point over the Missouri River between Fort Pierre and Pierre.

Back in 2016, the South Dakota Department of Transportation (SDDOT) performed a bridge replacement study, with intentions of gathering more information to justify a structure replacement. After years of studying and planning, the SDDOT decided to move forward with building a completely new bridge. The new structure will have updated features for functionality, user enjoyment, and aesthetics; and will be constructed just 10 feet north of the existing John C. Waldron Memorial Bridge.

Initial construction will not be visible to the public as it will begin underwater. This substructure work will consist of placing drilled shafts which will set the foundation for the rest of the project.
