Problems on the A14 this morning are continuing to have knock-on effects elsewhere in Cambridgeshire.
There are long delays of about two hours on the A14 in both directions due to an overturned lorry close to junction 29 at Bar Hill.
Queues are stretching back to junction 32 (Histon Interchange) on the westbound carriageway and to junction 23 (Spittals Interchange) eastbound.
Long delays on the A1 in both directions around the B661 at Buckden are adding to the problems on the A14.
And all lanes have now re-opened on the M11, having been closed earlier to stop traffic joining the A14, but there is still slow traffic, northbound, between junction 11 at Harston and junction 13 at Madingley.
