Police closed a section of the M8 motorway for several hours as they responded to 'concern for a person' in the area.
A stretch of the motorway was closed in both directions between Junction 3a, beside the Lothian town of Bathgate, south of Edinburgh, and Junction 4a at Whitburn. Roads into Bathgate were also been closed off while officers attended the incident, which started at around 11.25am and was brought to an end 2.45pm.
The response was understood to relate to concern for a person on the carriageway. Traffic data on Google Maps suggested that tailbacks more than two miles long built on the westbound carriageway, which was the focus of police attention.
