A lorry has overturned on the roundabout beneath a motorway junction in Northamptonshire.

The lorry was about to join the M1 from the A43 at junction 15a when it turned on to its side causing widespread congestion by blocking the road.

Roads leading to junction 15a were shut to allow the lorry to be recovered.

The lorry driver suffered only minor injuries and police said they did not expect the road to reopen before lunchtime.

A spokeswoman said: "Diversions have been set up and motorists aiming to travel south are being advised to travel to junction 15.

"Traffic aiming to travel northbound are being advised to join the motorway at junction 16."
