Safety Zone; Brandon Road Lock and Dam to Lake Michigan Including Des Plaines River, Chicago Sanitary and Ship Canal, Chicago River, and Calumet-Saganashkee Channel, Chicago, IL

DEEPER READ

This regulatory rule establishes a temporary safety zone on a specific half-mile stretch of the South Branch of the Chicago River in Chicago, Illinois. The purpose is to create a protected area around ongoing bridge assembly work for the Lake Street Bridge, which is being repaired by the Chicago Department of Transportation. The safety zone prevents vessel traffic from entering the work area, reducing the risk of collisions, accidents, or interference with construction crews and equipment. The legal authority for this action comes from the Coast Guard's statutory power under 33 U.S.C. 1231 and 46 U.S.C. 70034, which allow the agency to establish safety zones on navigable waters of the United States to protect public safety and the marine environment. The Coast Guard, operating under the Department of Homeland Security, routinely issues these kinds of temporary rules in coordination with local governments and project managers. The rule directly affects commercial vessels, recreational boaters, and any other watercraft that regularly use this section of the Chicago River. Mariners who need to pass through the area during the enforcement period must contact the Captain of the Port Lake Michigan or an on-scene representative to request authorization. Unauthorized entry into the safety zone can result in civil or criminal penalties under federal law. The enforcement period is tied to the duration of the bridge assembly work, meaning the zone will only be active when construction activities require it. The Coast Guard typically uses a combination of patrol vessels, buoys, and broadcast notices to mariners to alert the public to active safety zones. This stretch of the river is part of a larger connected waterway system that links Lake Michigan to inland navigation routes. Overall, this action has minimal broader policy implications and represents standard operational coordination between federal maritime authorities and local infrastructure agencies. It is narrow in geographic scope and temporary in nature, with minimal disruption expected for most users of the Chicago waterway system.
