The M6 northbound is closed after a lorry crashed through the barriers on the Thelwall Viaduct in Warrington and fell to the embankment below.
Emergency services were called to the bridge after the vehicle fell almost 200ft from the busy road at around 7pm on Monday night.
On arrival, police and firefighters discovered the lorry overturned on the grass bank below the viaduct, but managed to free the driver who was then placed in the care of paramedics.
Cheshire Police said the driver of the lorry was not believed to have suffered life-threatening injuries despite the fall.
The force has said three lanes of the northbound carriageway will remain closed until the morning due to the damage to the barrier.
As a result, at 10pm, there were long queues on the northbound side of the motorway.
A Cheshire Police spokesperson said: “Motorists are advised to avoid the area and find an alternative route during this time.”

Full statement from Cheshire Fire and Rescue
Firefighters were called to reports of a heavy goods vehicle (HGV) that had left the carriageway of the M6 northbound between Junction 20 and 21, close to the Thelwall Viaduct. On arrival, they found that a HGV had left the carriageway and overturned on an embankment, falling approximately 60 metres.
Crews used technical rescue equipment to lower themselves and reach the casualty, who was handed over to the care of attending paramedics.
Crews have applied water to cool the HGV and are using bunding to contain a leak of approximately 1000 litres of bio-diesel from the fuel tanks of the vehicle.
While the carriageway was fully closed, lanes one and two have since been re-opened by Cheshire Police and the Highways Agency.
