Project description

This project consisted of the construction of four bridges at Stratford in London, providing key routes between Stratford Regional and International Stations, the Westfield Stratford City shopping centre, and the Queen Elizabeth Olympic Park. The bridges included an 87 metre span, single spine, bowstring arch bridge over Network Rail and live CTRL (Channel Tunnel Rail Link) lines, and a 130 metre span town centre link bridge over Stratford Regional Station. This was launched over 11 live Network Rail, London Underground and Docklands Light Railway lines.
Two additional footbridges and associated works, involving retaining walls, cycle tracks, footpaths and drainage were also constructed.

The four bridges are summarised as follows:

Bridge 20: A striking 18 metre-high arch spanning 87 metres over the Channel Tunnel Rail Link and Docklands Light Rail lines serving Stratford International Station. It includes four road lanes (two in each direction), as well as two footpaths and a cycle path.

Bridge 17: The Town Centre Link bridge, measuring approximately 130 metres long, 12 metres wide and comprises around 1,700 tonnes of steel. The construction of the bridge was one of the most challenging structural engineering projects in the UK, as it crossed 12 live railway lines and Stratford Regional Station. The bridge was constructed in three sections and push-launched over the railway station, while trains remained operational.

Bridge 14: a 57 metre long, 6.7 metre wide, 203 tonne steel footbridge, lifted into place with a tandem lift by an 800 tonne and 700 tonne crane.

Bridge 13: a 40 metre composite footbridge over the River Lea, lifted in by an 800 tonne crane.

Responsible business



The project’s design allows surface water run-off to enter reed-bed settlement ponds before discharging into the River Lee.



The bridges were constructed from a large proportion of weathering steel, to negate the need for paint maintenance over the railway.
