Islamorada Transmission Main Replacement Project reaches halfway mark two months ahead of schedule
(UI) – 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.
This project is being funded with $35 million in grants and $7 million through low-interest loans. To abide by the grant requirements, materials have been sourced from U.S.-based companies, including the American spiral-welded steel pipe from South Carolina and the iron and steel butterfly valves.
The Islamorada Transmission Main Replacement Project is slated for completion in February 2025, but traffic impacts are expected to lessen after March 2024.
