South Wales Trunk Road Agent (SWTRA)

South Wales Trunk Road Agent (SWTRA) is responsible for managing, maintaining and improving the strategic road network in South Wales on behalf of the Welsh Government

About us

SWTRA manages, maintains and delivers improvements on the strategic road network in South Wales on behalf of the Welsh Government.

Our service covers the four key areas of network management, asset management, area operations and business management.

Network management

Our Network Management function is responsible for day-to-day monitoring and the availability of the road network. It includes operation of the South Wales Traffic Management Centre control room, the Traffic Officer Service and coordination of works on the highway.

Asset management

The agency is responsible for maintaining the condition and value of the Welsh Government’s trunk road assets. Assets include:

  • The highway
  • Bridges and structures, including tunnels
  • Electrical (street lighting, pedestrian crossings, lighting units, vehicle activated signs)
  • Intelligent transport systems
  • Traffic signals
  • Geotechnical features
  • Safety barriers
  • Signs
  • Soft estate (including highway verges and planted landscape areas)

Capital schemes are designed to improve a part of the trunk road network and enhance its value over an extended period of time (as opposed to maintenance of the existing asset). They include the cost of procuring, constructing and installing the new element of the network, whether for replacement of worn or obsolete assets or as an addition to the existing network.

Area operations

Our Area Operations function inspects and ensures the condition of structural, electrical and technology assets. The Area Teams are responsible for the implementation and annual delivery of routine and cyclic maintenance programmes through Service Level Agreements with the Agency's Service Providers. The other primary requirement of the Area teams is to deliver its delegated functions on behalf of the Welsh Government to undertake the requirements of the Highways Act 1980 & New Roads and Street Works Act in relation to coordination, agreement and enforcement of highway related issues.

Business management

Our Business Management function provides essential support to whole Agent. It encompasses finance, contract performance management, third party claims, business planning, health and safety, customer services, ICT support, office management and integrated management systems.

SWTRA is managed from its head office in Llandarcy, off M4 Junction 43. It is supported by regional operational offices at St Clears and Wilcrick. Network control is operated from the South Wales Traffic Management Centre, Cardiff.

SWTRA staff are employed by Neath Port Talbot County Borough Council (NPTCBC). All vacancies across our service are advertised on the NPTCBC website.
