Long delays were reported on the A38 in Plymouth this morning following a four-vehicle crash.
The incident happened on the eastbound side of the carriageway between Manadon roundabout and Marsh Mills around 9am.
The crash, which involved at least four vehicles, blocked the road and caused tailbacks more than three miles long.
Video from the scene, filmed by ITV News West Country journalist Sam Blackledge, shows the extent of the queues:
Emergency services also attended, including officers from Devon and Cornwall Police and Highways England.
It is not yet known if anyone was injured in the crash.
All lanes reopened shortly before 10.30am.
