Project Updates:
Feb. 25, 2026:
The S.D. Highway 1889 (Euclid Avenue) urban reconstruction project within the city of Pierre is scheduled to begin its second year of construction. Weather dependent, work is scheduled to begin as follows:
Beginning the week of March 2, 2026:
• Euclid Avenue from Wynoka Street to Elizabeth Street
Traffic will be adjacent to construction work from March 2 through March 9, 2026. The week of March 9, 2026, this segment will be closed for reconstruction until the anticipated reopening in late July 2026.
• Wynoka Street from Evans Street to Euclid Avenue
New storm sewer installation will continue. Traffic will be shifted to accommodate construction work.
Beginning the week of March 9, 2026:
• Euclid Avenue from 4th Street to north of 8th Street
Two-way traffic will be adjacent to construction work for the entirety of the 2026 construction season.
• Elizabeth Street from east of Grand Avenue to Euclid Avenue
This segment will be closed to accommodate new city water and sewer, and then reconstruction of the street, with an anticipated reopening in late July 2026.
As these segments are completed, work will advance into other segments of the Euclid Avenue reconstruction project. A 10-foot width restriction will be in effect for the entirety of the construction season when a two-way traffic condition exists. During the closure of Euclid Avenue from Wynoka Street to Elizabeth Street, over width and through vehicles will be detoured for the duration of the planned closure.
Pedestrians will be detoured through and around the work zones as needed. The traveling public is asked to be alert through the work zone for longer queues of traffic, construction vehicles entering and exiting the work zones, and for workers adjacent to moving traffic.
