Original story: A three-vehicle crash Monday afternoon blocked all southbound lanes of Interstate 95 near the Martin and Palm Beach County line and sent two people to a trauma center by helicopter, Palm Beach County Fire Rescue said.
Crews responded at about 3 p.m. near mile marker 89, between the Indiantown Road and Bridge Road exits. The first arriving crews reported a three-vehicle crash with multiple injuries, said Capt. Albert Borroto, spokesman for Fire Rescue.
All lanes were closed so that rescue crews could land the Trauma Hawk helicopter, Borroto said.
