Firefighters joined police officers and paramedics at the scene of a single-vehicle collision.
A spokesperson for West Sussex Fire & Rescue Service said: “We were called at 3.18pm this afternoon to reports of a road traffic collision involving one vehicle on the A24 Findon Road near Findon Valley.
“Joint Fire Control mobilised two fire engines and a heavy rescue tender to the scene.
“The road is likely to remain closed for some time this afternoon, and drivers are urged to avoid the area.”
A spokesperson for the South East Coast Ambulance Service said: “Ambulance crews attended, assessed and treated two patients on scene before taking them to Worthing Hospital for further medical treatment.”
Photos taken at the scene showed a bus became stuck, when trying to turn around to avoid the road closure.
