Lock and Dam 3 Bulkhead Construction

The U.S. Army Corps of Engineers, St. Paul District, has awarded a $2 million contract to an Anchorage, Alaska company to construct bulkhead slots on the intermediate wall and river wall upstream of the miter gates in the auxiliary lock chamber at Lock and Dam 3 located in Welch.

The project work consists of the demolition of a section of the existing concrete, wall armor, ladders, handrails and electrical tubes within the footprint of the new bulkhead slots.

Visitor and observation decks at both locks will remain open during the construction.

A localized cofferdam and dewatering system is necessary for the construction in the auxiliary lock and will not impact navigation.

Construction completion is expected by Aug. 15, 2025.
