The M40 was closed in both directions on the afternoon of Sunday 19th July 2015 after a horse box trailer carrying two horses travelling on the Northbound carriageway tipped on to its side between Junction 2 (Beaconsfield) and Junction 3 (Loudwater).
One of the horses jumped over the central reservation onto the Southbound carriageway while the other was trapped in the horse box.
Firefighters were called at 3.01pm. One fire appliance with crew attended from Beaconsfield fire station as well as one from High Wycombe fire station, one from Gerrards Cross fire station and one from Amersham fire station and two officers. Thames Valley Police, the Highways Agency and a vet also attended the incident.
Hydraulic rescue equipment was used by firefighters to release the horse which was still on its feet in the horse box. The second horse was secured on the verge. The horses were later secured in replacement horse boxes.
The motorway has reopened following this incident.
