March 15, 2025 – April 15, 2025, Completed Work:

On Saturday, April 5, 2025, the traffic signals at Pierre street were removed and a two-way traffic configuration through the intersection was installed on the north half of Sioux Avenue (U.S. Highway 14/83) as the contractor began work on the south half. A 12-foot width restriction is now in effect with overwidth vehicles needing to utilize S.D. Highway 1806, S.D. Highway 204 (Oahe Dam), and S.D. Highway 1804 as the signed overwidth detour. 

Surfacing removal has been completed on Pierre Street from Sioux Avenue to one block north. Surfacing removal is also complete from the East Pleasant Drive and Euclid Avenue intersection north thru Capital Avenue. The contractor then began working on excavating in order to replace City of Pierre utilities at three concurrent locations: Sioux Avenue, Pierre Street, and Euclid Avenue from Pleasant to Capital Avenue. 

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

On Sioux Avenue: The contractor will install a temporary bypass sanitary sewer line under Sioux Avenue traffic while they adjust and install the new sanitary sewer line.

Due to the inclement weather received this week, the contractor for the Euclid Avenue project in Pierre was unable to set up traffic control as previously planned for Monday, March 31, 2025.

Traffic Plan Update:
On Thursday, April 3, 2025, traffic control on South Pierre Street will begin to be adjusted into a two-way traffic configuration with access from Dakota Avenue.

Detour signing and pavement markings will be in effect by Friday, April 4, 2025.

Weather dependent, the two-way traffic configuration for east and west commuters through the Sioux Avenue and Pierre Street intersection will be set up either Saturday, April 5 or Monday April  7, 2025. This configuration for east and west commuters through the intersection will be in effect until Thursday, July 3, 2025. Access to Pierre Street from its intersection with Sioux Avenue will be closed. Traffic signals at this intersection will no longer be utilized, and commuters will need to advance through the intersection at a reduced speed. Pedestrians needing to cross Sioux Avenue at the Pierre Street intersection will be detoured to the traffic signals at Highland Avenue and Central Avenue. 

During this two-way traffic configuration through the Sioux Avenue Pierre Street intersection, a 12-foot width restriction will be in effect. Over-width vehicles will be routed around the dam on a signed detour route utilizing S.D. Highway 1806, S.D. Highway 204, and S.D. Highway 1804.
