    Brief

    This contract opportunity involves providing diversionary works services for the Lower Thames Crossing (LTC) project. Diversionary works typically include the construction and maintenance of temporary or permanent alternative routes, utilities, and infrastructure needed to keep traffic, pedestrians, and services flowing during the main crossing construction. Suppliers should have experience in civil engineering, temporary infrastructure design, project management, and coordination with multiple stakeholders. The successful contractor will need to manage traffic flow, maintain public safety, and ensure minimal disruption to existing services while the primary crossing construction proceeds.
