Costain has been selected by Transport for London (TfL) to undertake investigation works and to plan the refurbishment of the A40 Westway dual carriageway and the Marylebone flyover – a vital London transport link used by over 96,000 vehicles entering and exiting the capital each day.

Costain has already contributed to the first stage of the project – the new £6m contract is for a further two preparatory stages; feasibility study and concept design.

Costain will undertake a number of investigations of the 21 structures along the 4.6km of the route that runs through Kensington & Chelsea, Hammersmith & Fulham and the City of Westminster.

These investigations will assess the condition of key parts of the existing structures and identify the potential scope for future refurbishment work. Costain will work with TfL to consult with key stakeholders to gain access to the structures such as Network Rail as well as more than 120 local businesses who occupy premises nearby. The investigation works will take place in the summer.

The feasibility study will take approximately 10 months to complete after which Costain will develop a concept design and model how best to deliver the refurbishment works.

Marcus Hollan, Project Manager at Costain, said: “The A40 Westway is a vital transport link for Londoners. Tens of thousands of people use it every day to get to work, take their children to school or make deliveries.  We are looking forward to working with TfL to help them improve the journey for people travelling in and out of London.

“This refurbishment will ensure that the Westway continues to keep Londoners moving in the decades to come.  We will bring our strong technical knowledge and experience of the project so far to bear in assessing the feasibility of this refurbishment and planning out exactly how best to achieve it.”

Dana Skelley, TfL’s Director of Asset Management, said: “We are pleased to be working with Costain on this important and complex civil engineering project. It is a key part of the Westway’s ongoing maintenance.”
