  • SummarySummary
    Located approximately 1.1 km apart, the A19 Testo's and Downhill Lane junctions experience significant congestion, particularly during peak times, leading to unreliable journey times.

    Highways England identified the need for major improvements to reduce the traffic. The improvement programme includes two key schemes:



    • Testo's Roundabout
    • Downhill Lane Junction

    Wentworth played a key role in the successful delivery of the project, collaborating closely with Costain to review and align deliverable dates, ensuring the project adapted to evolving requirements. Health and safety were consistently prioritised, with a live design risk assessment document maintained and regularly updated for the client.

    We ensured strong communication throughout, holding weekly meetings and providing regular updates, which facilitated transparent progress tracking and timely project delivery.

    Through the support of the project Wentworth was awarded two Costain Blue badges for continued high quality delivery.

    Key scopeKey scope

    • Geotechnical designs, including slope stability, retaining wall methodology, sheet piling, and a CAT 2 check of proprietary equipment schemes (e.g., trench boxes and sheet piling with frames).
    • CAT 3 checks of the flyover superstructure construction methodology, including bridge elements, lifting points, trestles, and permanent formwork.
    • Design of foundations for a temporary bridge trestle and a 'clay stank' using sandbag walls to redirect water flow.
    • Reinforcement stability and sequencing for pier walls, wing walls, and pile caps.
    • Edge and services protection.
    • Road Restraint Risk Assessment (RRRAP) for the Vehicle Restraint System (VRS).
    • Approval in Principle (AIP) for the A19 flyover and South Bridge.
