Didcot (Oxford Daily News) February 18, 2026 – A collision on the A34 in Didcot has led to one lane being blocked, sparking significant delays for drivers in Oxfordshire this morning. Emergency services rushed to the scene near the Ladygrove Roundabout, where a vehicle incident disrupted northbound traffic during rush hour.

What caused the A34 crash in Didcot?

Initial reports suggest a two-vehicle collision initiated the blockage on the A34 northbound near Didcot. As detailed by Sarah Turner of Oxford Mail, the crash involved a lorry and a car, with the lorry veering into the central reservation before blocking the lane.

Jenkins emphasised the role of early morning mist, common in the Thames Valley during February. The Highways Agency’s live traffic map corroborated this, logging the crash under code ‘lane closure due to collision’. Further details from Oxfordshire Live’s Tom Davies revealed skid marks at the scene, suggesting possible aquaplaning on damp roads following overnight rain.

How severe are the delays from Didcot A34 blockage?

Delays have ballooned to over 45 minutes on the A34 northbound approaching Didcot, with tailbacks reaching Abingdon. Southbound lanes saw minor spillover congestion, adding 15 minutes to journeys towards Newbury.

Motorists reported gridlock spilling onto the A4130 Milton Interchange.  Live camera feeds from the scene, accessed via Highways England cams, showed a sea of brake lights under grey skies.

By 10am, delays peaked at two miles of stationary traffic, per RAC Traffic Watch. Holt’s updates tracked the snarl-up in real-time, reflecting commuter frustration.
