Drawbridge Operation Regulation; Atlantic Intracoastal Waterway, Palm Beach, FL

The Coast Guard is modifying the operating schedule that governs the operation of the Flagler Memorial (SR A1A) Bridge, mile 1021.8, the Royal Park (SR 704) Bridge, mile 1022.6, and the Southern Boulevard (SR 700/80) Bridge, mile 1024.7, across the Atlantic Intracoastal Waterway, at West Palm Beach, Florida. This modification allows the Flagler Memorial, Royal Park and Southern Boulevard Bridges to operate on alternative schedules when the President of the United States, members of the First Family, or other persons under the protection of the Secret Service visit Mar-a-Lago. The modifications are necessary to accommodate the increase in vehicular traffic when the presidential motorcade is in transit.
