In most instances filming requirements can be met by controlling traffic rather than closing roads and this can be discussed with the local authority and Police. The Wales Screen Commission has direct links to officers in Highways and Properties departments. Officers are usually able to grant permission for filming on council property and for road closures, provided the road in question is not a trunk road (main arterial route). If you do need to close a trunk road, permission must be sought from the Welsh Government and film makers should bear in mind that applications may take several months.
