Coast Guard: Stay Away From Exploding Power Lines

## Summary

On January 9, 2025, the Coast Guard will set up a temporary safety zone around Cypress Passage on the Atchafalaya River to keep boats and people safe during the demolition of overhead powerlines. No one can enter this 500-yard zone unless they get special permission. This one-day safety measure helps prevent accidents and keeps the river safe without causing long delays or extra costs.

## Abstract

The Coast Guard is establishing a temporary safety zone for navigable waters within a 500-yard radius of 29[deg]47'38.18" N, 91[deg]21'50.52" W, approximately MM 105.5, on the Atchafalaya River, locally known as Cypress Passage, during an overhead electrical powerline structure demolition operation on Thursday, January 9, 2025. The safety zone is needed to protect personnel, vessels, and the marine environment from potential hazards created by the demolition of the powerline structures resulting in electrical powerlines on the navigational water's surface. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port Marine Safety Unit Houma.
