BOCA RATON, FL (Boca Post) (Copyright © 2026) — Southbound lanes of South Federal Highway at Southwest 18th Street in Boca Raton were reported closed late Wednesday night due to an accident and multiple traffic lights being out, according to a traffic advisory from Boca Raton Police.
The advisory, sent at 10:38 p.m. Wednesday, said the southbound lanes at the intersection were shut down and urged drivers to seek an alternate route.
The notice did not include details on the crash, how long the closure was expected to last, or which traffic signals were affected beyond stating that multiple lights were out.
For Boca Raton and Palm Beach County drivers, South Federal Highway is a major north-south corridor, and a closure at Southwest 18th Street can push traffic onto nearby streets and increase delays for anyone traveling through the area, especially for late-night trips and early-morning commutes.
Boca Raton Police is the agency issuing the advisory and directing drivers away from the closed southbound lanes at that location. The advisory did not specify any additional agencies involved or provide information on injuries, vehicles, or whether the crash involved other roadway hazards.
What happens next is tied to clearing the crash scene and restoring normal traffic operations at the intersection, including the traffic lights that were reported out. Boca Raton Police did not provide a timeline in the alert.
Residents and drivers should plan for detours around South Federal Highway at Southwest 18th Street, allow extra time if they need to travel through that part of Boca Raton, and be prepared for changing traffic patterns as the closure and signal outages are addressed.
Updates, including when the southbound lanes reopen and when the traffic lights are back in operation, are expected to come through official Boca Raton Police traffic advisories.
