Coast Guard Slaps Speed Limits on Hampton River for Bridge Work

## Summary

The Coast Guard is setting up special rules on the Hampton River near Hampton Harbor to keep everyone safe during bridge construction. Boats will have to slow down and follow new traffic patterns, and sometimes they won’t be allowed near the bridge at all. These changes are temporary but important to protect people and vessels while work is happening.

## Abstract

The Coast Guard is establishing a temporary regulated navigation area and a safety zone on the Hampton River at the inlet to Hampton Harbor, Hampton, NH, in response to hazardous conditions created by construction activities for the Neil R.

The safety zone, when enforced, will prohibit all vessel traffic from transiting through or operating within 50 yards of the bridge(s) center span navigational channel. This rule is necessary to provide for the safety of life in the areas undergoing demolition and construction.
