The U.S. Coast Guard is expected to undertake work next month to repair, replace or remove hazardous channel markers in the Intracoastal Waterway, which some say are responsible for two boatssinking Memorial Day weekend off Long Beach Island.

The ICW is a 3,000-mile inland waterway running from Boston south along the Atlantic seaboard, around the southern tip of Florida and around the Gulf Coast to Brownsville, Texas. It runs through bay areas west of LBI.
