Parts of the A141 have been blocked after a combine harvester broke down this morning (July 12).
The vehicle broke down just after junction 23 for the A14 at around 8.50am.
It's not uncommon to see farming machinery during a rush hour commute in Cambridgeshire.
The breakdown has closed a lane on the roundabout, another on the A14 slip road, and there's reports of tailbacks for almost two miles on the A14 as traffic backs onto the dual carriageway
Police are on the scene, and recovery vehicles are on their way to move the stranded harvester.
In a statement, a spokeswoman for Cambridgeshire Constabulary said: "We were called at 8.52am to the junction 23 of the A14 amid reports of a broken down vehicle.
"When officers arrived, the vehicle turned out to be a combine harvester.
"It's currently blocking the A141 and we're advising people to avoid the area if possible."
Police could not confirm how long the road would remain blocked, or the amount of time it will take to move the combine harvester.
