A lorry has shed its load of stones on a motorway slip road, causing severe delays to traffic.

The stones are on the road near Epping between the M11 southbound carriageway and the M25 anticlockwise, at junctions six and 27 respectively.

One lane and a hard shoulder are closed on the slip road after the accident, with one remaining open.

The Highways Agency expects the stones to be cleared by 4.15pm.
