Traffic Change Update for U.S. Highway 14/83 Reconstruction Project in Pierre

PIERRE, S.D. – On Wednesday, July 9, 2025, traffic on the Sioux Avenue portion of U.S. Highway 14/83 in Pierre will be returned to its traditional five-lane configuration. South Pierre Street will be returned to its traditional one-way southbound configuration, restoring access from Sioux Avenue.

Due to continued construction, commuters will not be able to turn north at the Sioux Avenue/Pierre Street intersection. 

Traffic signals and pedestrian push buttons in the Sioux Avenue/Pierre Street intersection will not be operational until construction is complete immediately north of the intersection. In the interim, pedestrians desiring to cross Sioux Avenue at its Pierre Street intersection will continue to be detoured to the traffic signals at Highland Avenue and Central Avenue. Individuals needing access to the federal building and businesses north of Sioux Avenue on Pierre Street should utilize Central Avenue or Highland Avenue to Pleasant Drive.

The 12-foot width restriction on Sioux Avenue has been removed.

The traveling public is asked to be alert traveling through the work zone and watch for longer queues of traffic, construction vehicles, and workers adjacent to the moving traffic.
