The A14 near Bury St Edmunds has reopened following a collision between two cars earlier this morning.
Emergency services were called to the road near junction 44, the Bury Eastern Interchange, shortly after 8am on Thursday.
A spokesman for Suffolk police said that the carriageway was closed on both sides following the incident.
The air ambulance was also called to the scene.
A volunteer critical care paramedic, from the emergency medical charity SARS, was mobilised to assist the East of England Ambulance Service.
A spokesman for SARS said: “The SARS CCP, working with ambulance and fire crews, helped extricate a female patient before assessing her for serious leg and chest injuries.
“She was later escorted to hospital by the East Anglian Air Ambulance. Another patient is believed to have suffered minor injuries.”
Queues of around 25-30mins have been building along the road.
Three fire crews have also been called from Wickhambrook, Bury St Edmunds and Ixworth after receiving reports that people were trapped in a car.
Highways England confirmed the road had reopened in both directions at 10am.
