Part of the M2 was closed in both directions after a river of 'sewage' flooded the carriageway.
Highways England confirmed the motorway was closed coastbound and London-bound between junction 2 (Strood/Rochester) and junction 3 (Chatham/Rochester).
It happened at around 5pm.
It is understood to have been caused by a burst sewage pipe, which brought the waste gushing down from an embankment.
Mark Andrew posted the video below on Twitter, saying he heard a loud bang and then saw the sewage pouring down onto the motorway.
Officials have since confirmed the London-bound carriageway has reopened and two lanes remain closed coastbound.
The coastbound section was then closed for around an hour to allow a clean-up operation to be carried out.
It later reopened at 8.40pm.
