Lane Closures – 20th Street and Cliff Avenue Reconstruction

Published on April 15, 2026

Beginning on Friday, April 17, 2026, traffic on South Cliff Avenue will be reduced to one lane in each direction at 20th Street to allow crews to perform underground utility work as part of the 20th Street Reconstruction Project. The work in Cliff Avenue is expected to be complete in late May

Additionally, beginning on Friday, April 17, 2026, 20th Street will be reduced to one-way westbound traffic only between Cliff Avenue and Ninth Avenue to allow crews to reconstruct the street. This traffic pattern is expected to remain in place through late summer.

Access to all parking ramps in the area will be maintained at all times.

Work on this project includes underground utility improvements, concrete surfacing, sidewalks, and street lighting.

Emergency Services Access:
Emergency responders are advised to access the Avera Emergency Room from Seventh Avenue for the duration of this phase of construction. Motorists are encouraged to utilize 17th Street or 26th Street to access Seventh Avenue.

Pedestrian Access:
Pedestrian routes will be signed, and Audible Information Devices (AIDs) will be provided to assist those navigating the detour.

The project is expected to be completed in early November.

Drivers are encouraged to use caution, reduce speeds in the work zone, and consider alternate routes when traveling in the area.
