The forecast value of a major South Wales highways framework has risen by £135 million to £405 million as councils launch the formal race for contractors.

The South Wales Trunk Road Agency Highways & Structures Framework 2027 was previously advertised at £270 million but has now been increased by 50%, offering firms a significantly bigger pipeline of roads and bridges work, reports Construction Enquirer.

Neath Port Talbot County Borough Council is leading the procurement alongside Carmarthenshire and Monmouthshire councils.

Up to eight contractors will share the framework, which covers civil engineering, structural renewals, bridge strengthening, carriageway maintenance and road resurfacing across the strategic road network.

The largest lot, worth £252 million, covers highways and structures, including bridge repairs, tunnel works, safety improvements, lighting and intelligent transport systems.

A second £153 million lot covers resurfacing, drainage, pavement improvements, kerbing, road markings and emergency maintenance.

The framework will initially run for four years from April 2027, with options to extend for another two years to March 2033.

It will primarily serve the South Wales strategic road network across Cardiff and the Vale of Glamorgan, Swansea, Bridgend, Neath Port Talbot, Carmarthenshire, Monmouthshire, Newport and the Gwent valleys.

Contractors have until noon on 18 December to submit tenders, with award decisions expected on 8 March 2027.
