Crews have reached the halfway mark on the Florida Keys Aqueduct Authority's (FKAA) Islamorada Transmission Main Replacement Project approximately two-months ahead of schedule. With 11,000 linear feet of the new 36-inch transmission main now installed between MM 80 and MM 82, crews are continuing to work northbound toward MM 84.
In April 2023, crews began installing the new, cathodically protected transmission main via open-cut trench installation along US 1. Additionally, 900 feet of new transmission main has also been installed underwater at Tea Table Relief bridge crossing via horizontal directional drill (HDD), to protect it from high winds and storm surges. An additional main will also be installed via HDD at the Whale Harbor bridge crossing.
