Euclid Avenue reconstruction project gets underway in Pierre

Work on the $26.4 million U.S. Highway 14/83/Euclid Avenue reconstruction project in Pierre started today (March 31, 2025).

The contractor, Morris, Inc. of Fort Pierre, began in multiple locations on the south end of the project. Operations Manager TJ Gallagher says pedestrians are encouraged to cross Sioux Avenue using the traffic lights at Central Avenue and at Highland Avenue.

Gallagher says areas between Sioux Avenue and the railroad bridge should be open by early July.

Gallagher says those who use the Saint Charles parking area will have a way to get in and out.

Various closures are scheduled during the 2025 construction season.

A weekly update meeting will be held every Wednesday at 11am CT at the AGC Building (300 E. Capitol Ave, Suite 1) in Pierre.

More information about the work is available at:

• Morris Inc.: https://www.morris-inc.com/euclid-avenue-reconstruction-project/

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

At a recent informational meeting, Operations Manager TJ Gallagher shared the basics of the project’s two year timeline.

Gallagher said Phase Two will be done almost simultaneously with parts of Phase One, but the Phase Two work will be in the Pleasant Drive and Capitol Avenue area.

Gallagher says Pierre Street, south of Sioux Avenue, will become a one-way with no access from Sioux Avenue.

Traffic on Sioux Avenue will be reduced to a single lane in each direction during the early phases of the project.

The overall completion date is November 2026.
