Case Studies

Traffic management case studies

Below is a list of clickable case studies covering a selection of Traffic management projects completed by FM Conway. Please click on the link to review the full case study.


Neasden Super Scheme

Client Transport for London

Overview The A406 North Circular Road remains one of London’s busiest A-roads. At peak capacity, it experiences traffic volumes only 10 per cent lower than the M25. The Iron Bridge and the Dog Lane Arches in Neasden are two of the most important structures along this strategic road. They carry the A406 across the Jubilee and Metropolitan lines, while also carrying mainline rail lines into London. They are also nearly a century old. When the concrete waterproofing on both structures began to fail, it became clear that safety-critical refurbishment was needed. Disruption to the transport network was unavoidable during the works, but Transport for London (TfL) wanted to ensure that it was kept to a minimum. TfL commissioned FM Conway to carry out three key schemes on the A406: the renovation of the Dog Lane Arches; the refurbishment and lifting of the Iron Bridge; and the rebuilding of the retaining wall on Dog Lane itself. All three would be delivered simultaneously to minimise disruption to travellers, local residents and businesses and the need for additional road closures in the future.

Sheppey Route Ltd is the Design, Build, Finance and Operate (DBFO) contractor that manages the road on behalf of Highways England. Encompassing the Sheppey Crossing, it is an important transport link for residents and businesses and the main option for traffic travelling from the Isle of Sheppey towards the M2, M20 and beyond. With 30,000 drivers using the A249 each day, a streamlined and efficient approach to its maintenance and upkeep is vital.
