Pierre-Fort Pierre Bridge Project

Throughout the project, westbound lanes on U.S. Highway 14 across the Pierre-Fort Pierre Bridge will be intermittently reduced to one lane and traffic speeds may be reduced for bridge construction work.

Project Update

June 24, 2022: Summer is heating up in South Dakota, and so is work on the new Pierre-Fort Pierre Bridge. Crews have been continuing to work on the Pierre-side abutment footing, south wing wall, and stem wall. Concrete was placed for the south wing wall, and crews have been forming the lower abutment stem wall. The stem wall is the main body of the abutment. It functions to deliver the superstructure reaction loads to the foundation and to retain much of the soil behind the abutment. Crews have also been working on constructing the drilled shaft at bent four right. Next week, crews will begin constructing the drilled shaft at bent four left.

Public Safety Information

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 in progress in the Pierre-Fort Pierre area. The new bridge is anticipated to be open for traffic December 2023. Total project completion is anticipated for January 2025.

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.
