One lane is also blocked on the southbound side of the motorway at J16.
Flooding on the A45 between Mereway and the M1 is also causing congestion with one lane closed on the westbound carriageway.
And there has also been a crash on the A45 eastbound from the A43 Lumbertubs Way to the A5076 Great Billing Way.
Roads surrounding these areas are also blocked up, as well as on the A5123 in the town centre and Towcester Road, due to a stalled van.
