Drivers in Suffolk faced severe disruption after a serious overnight collision forced the A14 to close in both directions near Bury St Edmunds, creating long delays across one of the regionâs busiest transport routes.
The incident happened between junction 43, near the A134 Bury Central Interchange and Sugar Beet Roundabout, and junction 44, close to Moreton Hall and the A134 Bury Eastern Interchange.
Emergency services were called to the scene shortly before 2.30am after reports of a serious crash on the dual carriageway. Police, ambulance crews and highways officers attended the incident, while traffic officials confirmed the full closure at around 3am.
A 22-year-old man suffered serious injuries in the collision, according to local reports. Authorities have not yet released further details about the circumstances surrounding the crash or how many vehicles were involved.
The closure remained in place throughout the morning while investigators worked at the scene and recovery teams cleared the carriageway.
Traffic quickly began building along the A14 and nearby diversion routes, with congestion reported between Moreton and Battlies Green. Motorists travelling through Bury St Edmunds also faced delays around Southgate Street and surrounding town centre roads as diverted traffic spilled into local streets.
Major Suffolk route brought to a standstill
The A14 is considered one of the most important roads in the East of England, linking Suffolk with Cambridge, the Midlands and the Port of Felixstowe. The route is heavily used by commuters, freight traffic and regional drivers every day.
When incidents force the road to close in both directions, traffic pressure rapidly spreads beyond the motorway itself. Local roads around Bury St Edmunds are often unable to handle the sudden increase in diverted vehicles, leading to slower journeys across nearby residential and commercial areas.
The impact of the latest closure was felt particularly strongly because junctions 43 and 44 provide key access into Bury St Edmunds, Moreton Hall and several surrounding communities.
Drivers were urged to avoid the affected area wherever possible and follow official diversion signs instead of attempting shortcuts through residential streets.
National Highways said the road would remain closed âfor the morningâ while emergency services carried out their work. Motorists can continue checking live travel conditions through the National Highways traffic update service.

Police investigation under way
Suffolk Police remain at the scene as part of an ongoing collision investigation. Serious crashes often require lengthy road closures because investigators must carefully examine the scene before traffic can safely return.
Specialist officers may need to inspect skid marks, debris, vehicle damage and CCTV or dashcam footage to establish exactly how the incident happened. Recovery teams also need time to remove damaged vehicles and ensure the carriageway is safe.
Although road closures can cause frustration for drivers, emergency officials say preserving evidence is a critical part of investigating collisions involving serious injuries.
The East of England Ambulance Service was also contacted following the incident as emergency responders continued assisting at the scene.
Anyone who travelled on the A14 near Bury St Edmunds during the early hours of the morning and may have witnessed the collision or captured dashcam footage is being encouraged to contact Suffolk Police.
The crash is the latest example of how a serious incident on the A14 can quickly create disruption across Suffolkâs wider road network. Even relatively short closures on the route can affect local commuters, freight transport and town centre traffic for several hours.
Drivers heading towards Cambridge, Ipswich, Stowmarket or nearby Suffolk towns should continue allowing extra travel time while congestion clears.
