Illinois Waterway 2023 Consolidated Maintenance Closures Update

Dear Illinois Waterway Stakeholders,

As scheduled, Marseilles, Dresden Island, and Brandon Road Locks are now closed until 30 SEP 2023. Crews are already moving floating plant, removing gates, setting bulkheads, and preparing to dewater the lock chambers. I invite you to view a short (~2-minute) video about this summer’s project:, and share it widely with coworkers, business contacts, family and friends.

I want to thank the entire Navigation community for managing queues proactively and getting vessels where they needed to be prior to the closures.

We will continue to keep our webpage up to date: Navigation Status. I’ll plan to send updates in late June, late July, mid- and late August, and mid- and late September to keep you informed of our progress. Please feel free to call or e-mail if you have any questions.
