Sixth Street Bridge to Close February 13

The Sixth Street bridge will close on Monday, February 13, 2023, as the Unity Bridge project’s first phase begins.

The Unity Bridge project encompasses Sixth Street from the Big Sioux River to Weber Avenue. The project will reconstruct the current Sixth Street bridge, which is near the end of its lifespan; update underground utilities, including the installation of a looped watermain to ensure a reliable water supply to adjacent developments; and utilize streetscaping to enhance vehicle and pedestrian traffic.

“As construction starts, we encourage drivers and pedestrians to use caution in the area and consider alternate routes,” said Andy Berg, City Engineer for the City of Sioux Falls. “We thank residents for their patience and look forward to delivering this important project to our community.”

Highlights of the project include:

  • Elements for the future quiet zone/whistle reduction railroad crossing
  • Lighted piers
  • Landscaping
  • Diagonal parking along Sixth Street
  • Plaques paying tribute to leaders who exhibit community spirit and unity that make Sioux Falls a welcoming home. (Plaque honorees to be determined at a later date.)

While the bridge will be closed beginning Monday, access to LSS and Cherapa Place will be maintained via Sixth Street from Weber Avenue.

The River Greenway Recreation Trail, along the east bank of the Big Sioux River, will be closed from Eighth Street to the Falls Park entrance on Weber Avenue. A detour will be established that follows a route west of the Big Sioux River through downtown and along Phillips Avenue into Falls Park.

The project’s estimated completion date is July 2024. For project information and to sign up for email updates, visit
