Chicago Harbor is closed to everyone for fireworks

The Coast Guard will close a section of Lake Michigan in Chicago for a fireworks display. No boats or people can enter this area without special permission.

This is a routine closure for a specific event. It means that for a few hours, a small part of a major waterway becomes off-limits to protect people from a temporary hazard. These types of temporary safety zones are common for events like air shows, boat races, or fireworks.
