Pembrokeshire occupies an area of 616 square miles and its road network comprises trunk, principal, non-principal and unclassified roads. This network is chiefly rural in character, but contains a significant urban element.
The National Assembly for Wales is responsible for trunk road maintenance in Wales. The South Wales Trunk Road Agency (SWTRA) is responsible for the maintenance of the majority of the trunk road network within Pembrokeshire.
The Trunk Road A487 from Capel Newydd to the County boundary is maintained by the Mid Wales Trunk Road Agency (MWTRA). Pembrokeshire County Council acts as sub-agents for operational activities relating to winter maintenance within its County boundary for SWTRA.
Pembrokeshire County Council will endeavour to provide a Winter Maintenance Service which, as far as is reasonably practicable, will permit the safe movement of vehicular traffic on the strategically important sections of the highway network and keep to a minimum delays and accidents due to adverse weather conditions.
