There are lengthy delays near Cambridge this morning after a lorry crashed into the central reservation of the A14.
The collision happened on the westbound carriageway at Bar Hill (junction 29).
Police have warned drivers to expect disruption, and a diversion is in place.
Highways England say that it is likely to take "several hours" to recover the lorry due to the fact that it is stuck on the barrier.
There is heavy congestion in the area and queues are stretching back to junction 31.
