THE M4 has reopened after an earlier crash closed the road in both directions.
Both eastbound and westbound carriageways were closed between J16 Swindon West and J17 Chippenham over the lunch period.
Wiltshire Police have said there had been a multiple vehicle collision.
Emergency services attended the scene and one woman who was trapped in her car, was released and taken to the Royal United Hospital in Bath with minor injuries.
Heavy delays were experienced in and around the area, particularly in Royal Wootton Bassett following the closure of Dauntsey bridge.
