Sheriff’s Office Sets Marathon Halloween Traffic Changes

Traffic changes planned

The Sheriff’s Office will implement temporary traffic pattern changes in Marathon during Halloween 2026. The plan also includes restricted access to neighborhoods behind Florida Keys Marathon International Airport.

The changes are temporary and are tied to Halloween activity in the Marathon area. Residents and visitors who use the roads near the airport should expect traffic to move differently while the advisory is in effect.

Neighborhood access

The Sheriff’s Office also plans to limit access to neighborhoods behind the airport. The advisory identifies the general area but does not list the streets covered by the restriction.

It also does not state when the traffic patterns or neighborhood restrictions will begin or end. Those details will determine how residents, visitors and other drivers plan travel through the area.

What drivers should check

Drivers should look for additional directions from the Sheriff’s Office before traveling near the Florida Keys Marathon International Airport during Halloween 2026. A later notice could identify the affected roads, the restriction period and any instructions for people who live in the restricted neighborhoods.
