The A12 is now open after a man who threatened to jump off a bridge there was brought to safety by police.
Police were called to the scene at 1pm and after almost four hours of talking to the man he was coaxed away from the bridge and is now safe.
The incident at the Leytonstone bridge junction with Mission Grove closed the normally busy A12 road in both directions, from the Green Man roundabout stretching down to the Lea Interchange.
East London remains in gridlock, with traffic backed up to Ilford along the A406 in one direction and as far as Hackney in the other.
