Safety Zone Planned for Mackinac Bridge Swim Event

## Summary

On July 18, 2026, a safety zone will be set up around the Mackinac Bridge from 7 a.m. to noon to keep swimmers and boats safe during a big swim event. Boats and people can’t enter the 100-yard zone unless they get special permission. This temporary rule helps protect everyone and the environment without costing money but asks for public comments by June 4.

## Abstract

We invite your comments on this proposed rulemaking.

The Coast Guard w…
