National Highways traffic officers and contractors assisted the emergency services with traffic management.
Cambridgeshire Police turned vehicles around and investigated the scene of the crash.
Steph, a driver from Suffolk, who only wanted her first name used, said she was stuck for “eight hours”.
“The problem was the lack of information so I ended up sleeping in a switched off car which was incredibly cold”.
She said she was left “tired and confused” and struggled to reheat her body.
She added that she was most “concerned about those involved in the crash”.
An EEAS spokesman confirmed that two ambulances, two Hazardous Area Response Team vehicles, one ambulance officer vehicle and a response car were sent to the scene.
“An adult and a child were transported to Addenbrooke’s Hospital for further care”, he said.
A spokesperson for National Highways thanked motorists for their patience.
