The A1M was closed northbound just before Norman Cross at Junction 16 for over two hours this afternoon.
The closure today (Friday, September 1) was due to a broken down vehicle in the middle of the carriageway.
A police spokesman said: “We were called at 12.36pm with reports of a broken down vehicle on the northbound carriageway of the A1M near Norman Cross.
“A Range Rover lost a wheel and is blocking the carriageway. Highways are at the scene.”
The road was cleared and re-opened at around 2.45pm.
