The City of Sioux City Engineering Division announces the start of the 6th Street Bridge Reconstruction - Bridge Deck Replacement Project on March 16, 2026, weather permitting. This project includes the removal and replacement of the bridge deck, barrier rails, sidewalk, and light poles. In addition to these improvements, the bridge will also be reconfigured to accommodate a 10-foot bike trail on the south side of the bridge.
Construction is scheduled to be completed in one stage and will close 6th Street to all through traffic from Hoeven Drive to Chambers Street. In addition to the closure of the bridge, a portion of the right northbound lane of Hoeven Drive from 4th Street to 6th Street will also be closed. All work is anticipated to be completed by November 2026. The 6th Street Bridge Reconstruction - Bridge Deck Replacement project was awarded to Dixon Construction on December 8, 2025, in the amount of $2,644,540.90.
A detour utilizing Lewis Boulevard, 3rd Street/4th Street, and Hoeven Drive will be posted. Motorists are advised to reduce speed, drive cautiously, and obey all traffic control signs with regard to this closure.
