Temporary Security Zone on the Ohio River Near Cincinnati

The Coast Guard is establishing a temporary security zone on the Ohio River that covers the full width of the waterway from mile marker 461 to mile marker 473. The zone is active from 12:01 a.m. on May 8, 2026, through 11:59 p.m. on May 11, 2026.

Why it matters: This action does not change long-term river traffic patterns or create lasting restrictions. It simply pauses normal navigation in a specific stretch of the Ohio River for four days to allow the Secret Service to secure a water route for a visiting official. Commercial and recreational boaters in the area will need to check Coast Guard radio broadcasts for active enforcement windows and request permission if they must transit through the zone.

Who it affects

• Recreational boaters and commercial vessel operators navigating the Ohio River between mile markers 461 and 473

This action comes from the U.S. Coast Guard’s Captain of the Port Ohio Valley and is published in the Federal Register; mariners should verify the original document and Coast Guard broadcasts for exact enforcement times before planning river transit.
