Main Text

Chiswick Bridge is a Grade II listed bridge located on the A316 arterial route into London, and is a strategic River Thames crossing. This bridge is a 4-lane carriageway used by 40,000 vehicles, hundreds of pedestrians and cyclists each day. The bridge also provides an excellent vantage point for public river events and attracts large crowds, most notably for the prestigious annual Oxford and Cambridge University Boat Race.

During its 52 week construction programme, only three planned weekend closures of the bridge were required to carry out essential works to the bridge expansion joints and to resurface the carriageway. The works were carefully planned and managed around bridge users, and rigorous safety measures were put in place to ensure safe working for the operatives and safe access for members of the public.

To ensure minimal disruption, lane restrictions were kept to a minimum, and lane reductions only during off-peak times. All work activities were co-ordinated to prevent delays and disruption to the London road network and the River Thames.

Chiswick Bridge is a popular viewing point for the prestigious Oxford and Cambridge University Boat Races. The construction programme was developed in collaboration between TfL, BAM Nuttall, supply chain partners and all third parties and stakeholders to ensure the works were completed in advance of the 2015 Boat Race, so the public could enjoy the race from Chiswick Bridge as tradition.

Improved Safety

The new lighting columns have been positioned closer to the bridge parapets, creating a cycleway which is now a suitable width and without any street furniture or obstacles, creating an enhanced cycling experience for users. Likewise, pedestrian flow is now segregated and an increase in pedestrian flow is expected due to the safer, dedicated footways.

As Chiswick Bridge is a Grade II listed structure, the design of the parapet strengthening had to provide the necessary degree of vehicle containment whilst maintaining the heritage look. A stainless steel skeleton was used within the stone elements. Chiswick Bridge is the first in the UK to use this method to provide full containment in the event of an incident, whilst limiting the impact on the heritage value of the structure.

We employed 4 apprentices on the Chiswick Bridge project and provided summer placements for university students. These apprentices have continued working with us on the Structures and Tunnels Investment Portfolio Framework.
