Emergency services were called mid-morning following after the truck toppled over heading round the roundabout under the A14, taking out a street light in the process.
Highways England closed the road heading away from Wellingborough at around 11am and indications are it will not reopen until much later.
The exit slip road from the A14 westbound is also closed. Traffic is being diverted via local routes.
