Three lanes of the M1 motorway were closed in South Yorkshire this morning after a pile-up.
Highways England said emergency services were at the scene of a multi-vehicle collision on the southbound carriageway.
It had closed three lanes between junctions 35 and 34 while paramedics and police responded.
All lanes were reopened shortly after 9.30am but drivers were warned that there were tailbacks to junction 35.
The disruption is not expected to be cleared until around 10am.
