The Florida Keys Aqueduct Authority’s southbound rolling lane closure, just north of Mile Marker 80, which has been in effect for the Islamorada Transmission Main Replacement Project since May 1, will be suspended for Memorial Day weekend from Saturday to Tuesday, May 27-30.
The closure along U.S. 1 is rolling, meaning the lane is closed for 1,000 to 1,500 feet at a time as crews install the new transmission main. The lane closure will continue to shift northbound from Mile Marker 80 to Mile Marker 84 in 1,000 to 1,500-foot increments for the duration of the project.
The Islamorada Transmission Main Replacement Project is estimated to be completed by February 2025; however traffic impacts will lessen by March 2024. Work will halt for major holidays and events. One northbound and one southbound lane will remain open along U.S. 1 for the duration of the project, and bike lanes will remain accessible.
