Fort Lauderdale, Florida – Drivers in Fort Lauderdale should plan ahead for upcoming traffic changes as a portion of NW 21st Avenue is scheduled to close starting Thursday, May 1, 2025, due to major infrastructure work related to the Prospect Lake Clean Water Center Water Main Project.

According to city officials, the closure marks the beginning of Phase 6 of the ongoing project, led by David Mancini and Sons, Inc. Construction crews will begin installing a 48-inch water main at the intersection of NW 21st Avenue and Prospect Road, an effort that is expected to enhance water delivery and support future clean water initiatives in the area.

As part of the work, northbound lanes on NW 21st Avenue will be closed for approximately two weeks, causing significant traffic rerouting in the area.
