The M20 was closed in both directions after a distressed woman was seen crossing a footbridge.

All vehicles were stationary near junction 4 for Leybourne.

At its height, there were four miles of congestion on the approach London bound.

Tailbacks stretched just over a mile on the coastbound carriageway.

Police were called at 8.56pm on Saturday and closed the motorway as a precaution while they spoke to the woman.

She was brought to safety by 9.50pm and the road was reopened.
