# What happened A crash on the A34 near Didcot on Friday 11 September involved a motorcycle and a van. It occurred at about 3pm and resulted in a motorcyclist being taken to hospital with serious injuries. Emergency services, including the Thames Valley Air Ambulance, responded to the scene.
# Emergency response and road closures The presence of the air ambulance required emergency crews to close both carriageways of the A34 while they treated the injured rider and secured the scene. Police confirmed southbound traffic was reopened at about 4:30pm, but vehicles were still moving slowly. National Highways said the northbound carriageway remained closed into the evening to allow police collision investigation works.
# Traffic impact Queues built up strongly, with southbound tailbacks at one point extending beyond Abingdon. Some drivers faced delays of around an hour and a half. Police advised drivers planning to travel that route to find alternative routes where possible while closures were in place.
# Police statement and investigation Thames Valley Police said emergency services had closed both sides of the carriageway for a short period and that a person had sustained serious injuries and was in hospital. The force said it would provide an update when one was available. National Highways coordinated with police to keep the northbound carriageway closed for collision investigation work.
# Immediate follow-up and context Local reporting linked this incident to other recent serious motorcycle collisions in the area and highlighted a separate police appeal for witnesses to a related A34 collision. At the time of reporting, Thames Valley Police was still managing the scene and gathering information.
# Practical implications for readers If you travel the A34 between Milton, Chilton and Abingdon, expect potential delays or closures while emergency and investigative work continues after serious incidents. Check National Highways and local police traffic updates before travelling and consider alternative routes in the short term.
# Bottom line A serious collision on the A34 near Didcot on 11 September led to a significant emergency response, an air ambulance landing, and prolonged road closures. The motorcyclist was hospitalised with serious injuries and police continued an investigation at the scene into the evening.
