The Florida Highway Patrol is investigating a crash with multiple injuries on the Florida Turnpike in Clermont.

At least seven vehicles were involved in the crash, though it's unknown what series of events led to the crash.

All southbound lanes were blocked while crews worked to clear the roadway and set up a temporary lane of travel down the east shoulder.

Florida Highway Patrol said one woman was flown to ORMC in serious condition and two others were taken to South Lake Hospital by ambulance.

Traffic was backed up almost 4 miles at one point, but has since cleared. All lanes have reopened.
