A lorry has overturned on the M11, blocking three of four lanes and causing severe delays.

The heavy goods vehicle crashed on the northbound carriageway, between junction six for the M25 near Epping and junction seven in Hastingwood.

Congestion is affecting traffic back to Loughton, and there are also delays southbound.

The lorry is believed to have hit the central reservation of the motorway.

The Highways Agency said disruption will remain until later this afternoon.

More to follow.
