North Yorkshire Police are investigating a serious road traffic collision involving two motorcycles and a car.
It occurred on the A162 at Tadcaster - on the bridge which goes over the A64 - at about 12.30pm on Saturday 21 July 2012.
It is believed the two motorcycles were travelling together along the A162 away from Tadcaster in the direction of Sherburn and the blue Peugeot 307 estate had left the A64 and turned right onto the A162 to go towards Tadcaster.
One of the motorcycles was in collision with the Peugeot and the other rider crashed after taking avoiding action.
Both male riders are from Northamptonshire. A 42-year-old was taken to York District Hospital by land ambulance where he is receiving treatment for hand and shoulder injuries. A 50-year-old was taken to Leeds General Infirmary by air ambulance with serious hand and leg injuries.
The 50-year-old male driver of the Peugeot, from the York area, was uninjured but left shaken by the collision.
Highways placed a diversion around the crash scene to allow police officers to investigate the circumstances of the collision and for all three vehicles to be recovered.
The road is expected to reopen at about 6pm on Saturday.
Witnesses to the collision or anyone with information that may assist the police investigation, are urged to contact North Yorkshire Police on 101, select option 2, and ask for Hamish Halloway or Alison Travis.
