    Brief

    Wiltshire Council is procuring a contract for the M4 Junction 17 improvement works, valued at approximately £27 million (including VAT), with contract award expected in early spring 2026. This is a two-phase project: Phase 1 (Spring-Autumn 2026) involves Early Contractor Involvement (ECI), and Phase 2 (2027 onwards) covers construction, subject to Department for Transport Full Business Case approval. The scope includes installation of traffic signals on all roundabout approaches, carriageway widening throughout the junction, increasing traffic lanes across motorway bridges from two to three, and widening the circulatory carriageway. Contractors must be capable of working on the National Highways network and demonstrate significant experience delivering complex highway infrastructure improvements. This is a substantial infrastructure project requiring contractors with proven expertise in major road works and traffic management systems.
