S.D. Highway 1889 - Euclid Ave
Project Updates:
April 17, 2026:
Anticipated Work - May 2026:
On Euclid Avenue (from Broadway Avenue through Elizabeth Street):
Water line and storm sewer installation will continue. Undercut work will be completed, and base course placement may begin at Wynoka Street and continue north.
On Euclid Avenue (from Elizabeth Avenue to Fourth Street):
The traffic signals at Elizabeth Street will be removed. There is currently no work in this segment. The road is closed to westbound Elizabeth Street to accommodate the installation of new city sewer and sanitary lines. Because the west half of the Elizabeth intersection is closed for waterline and sanitary sewer installation, traffic will free-flow adjacent to the intersection work from Euclid Avenue east onto East Elizabeth Street.
On Euclid Avenue (from Fourth Street north to the divided four-lane north of Eighth Street):
Traffic control will continue with two-way traffic in the southbound lanes. Storm sewer placement will be underway between Fourth Street and Sixth Street in the northbound lanes. Backfill and subgrade compaction will also be underway. The contractor may then continue surfacing removal through Eighth Street.
On Wynoka Avenue (from Euclid Avenue east to Hilgers Gulch):
The Highland Avenue intersection will be closed as storm sewer construction begins across Highland Avenue. Storm sewer placement will continue toward Euclid Avenue. Highland Avenue will then be reopened and gravel surfacing placed.
On Elizabeth Avenue (from Grand to Euclid):
This one-block segment will remain closed as the City of Pierre continues sanitary sewer and new water line installation.
