About this event

Hogarth Flyover is one of west London's most notorious flyovers, used every day by around 10,500 vehicles going eastbound from the A316 to the A4 Great West Road, crossing over the Hogarth roundabout.

The single-lane structure was built in 1971 as a temporary measure to reduce traffic congestion at the roundabout, with an estimated design life of around 10-20 years. The structure is still very much in use and heavily used after almost 45 years.

Following a detailed review and structural assessment by Conway AECOM, the structure was deemed to be in a seriously poor condition, prompting the need for vital refurbishment works to demolish and reconstruct the concrete deck.

Challenges included carrying out the repairs on the 250m structure within a six-week closure. The urgency of the programme was to avoid unplanned closure on safety grounds, whilst at the same time planning around other road closures for bridge strengthening work at Hammersmith Flyover and Putney Bridge.

Major successes included the D&B team's rapid mobilisation bringing together Early Contractor Involvement with specialist supply chain (demolition, temporary works, cranage), client (TfL structures client, highways, planned interventions, CDM, PR) to arrive at a solution that could be built within the clients programme and budget.

Hogarth Flyover was re-opened to the public on 31 August, 10 hours ahead of schedule. Our speakers will explain how this was achieved. They are Amrit Ghose and Yunus Hussein of AECOM.
