Police and Highways worked through the night to reopen the A1 southbound between Colsterworth and South Witham after a driver was found to be travelling the wrong way and hit several other vehicles.
It happened just after eight o'clock last night just south of Colsterworth and led to lots of debris on the carriageway.
