Our contractor-partners at work repairing the guidewalls at Lock and Dam 5, near Minnesota City, Minnesota, Dec. 14. The work includes divers ensuring the forms are properly placed and secured before concrete is pumped into voids within the guidewall structures, which serve as extensions of lock walls to guide vessels into the lock chamber and provide mooring for long tows. The repairs are also being done at Locks and Dams 4 and 5A to ensure our critical infrastructure remains serviceable, with work scheduled to end spring 2019 before the navigation season starts back up.
