The large caravan is close to Cranfield Park Avenue, Basildon, and is currently blocking most of the footpath on the west-bound carriageway.
It is not the first time a caravan has been dumped on the road, with a spate of them two years ago.
In December 2016, a caravan was dumped at almost the exact same place.
A few months before, in March, one just after the Noak Bridge junction was set on fire.
A Basildon Council spokesperson said: “Basildon Council is aware of a static home which has been abandoned at the side of the A127.
"Officers have carried out an initial inspection and are arranging for it to be safely removed.”
