A1 closed in Nottinghamshire after collision

The A1 in Nottinghamshire is closed northbound between the A57 (Worksop) and A620 (Retford) junctions due to a traffic collision and diesel spillage.
Nottinghamshire Police are on scene, and teams from Highways England will also attend.
Traffic is being diverted via the ‘Solid Circle’ symbol:
– At the A57 (Apleyhead) junction take the second exit onto the A57
– Continue for 13 miles, to the junction with M1 J31
– At the junction, take the third exit onto the M1 northbound
– Continue for 1 mile to the M18 interchange (J32)
– Bear left onto the M18 (signed Hull, Doncaster, Rotherham)
– Continue on the M18 for just under 9 miles, to J2 (A1M)
– At the roundabout, take the first exit to rejoin the A1M northbound at J35
A statement from Highways England said: “This diversion will add around 30 minutes to normal travel time, in addition to any delays on approach to the closure, so please allow additional journey time.”
