Gloucester police have urged drivers to avoid the A40 following a serious collision involving seven vehicles. The crash has led to a complete closure of the road, causing significant disruptions in the area. Emergency services are on-site managing the situation, but authorities warn that the closure is expected to remain in place well beyond the morning, potentially affecting the evening rush hour. Motorists are advised to seek alternative routes and allow extra travel time until the scene is cleared and the road reopens.
