Drivers are advised that there are severe delays on the southbound M11 in Essex following a multi-vehicle collision that has resulted in a closure at junction 7 near Harlow.
Emergency services are currently on scene dealing with the collision which happened just after 4pm with current delays of around 60 minutes being reported.
It is likely the closure will remain in place well into the rush hour traffic.
A Highways Agency spokesman said: "We will fully reopen the motorway as soon as it is safe to do so."
Traffic is being diverted using the A414 towards Chelmsford and the A12 south to the M25 junction 28.
