A collection of Macalloy Tie Rods and Post Tension Bars went into making a truly iconic bridge which forms part of London’s modern architectural landscape.
After years of having a reputation of being narrow and dangerous, the decision was made to replace the footbridges that ran either side of the Hungerford Bridge in London, with new structures. The bridges connect Charing Cross and Embankment stations to the north and Waterloo on the south.
A competition was launched in 1996 to design two new footbridges that would flank the existing Hungerford Bridge and commemorate the 50th anniversary of the Queen’s coronation.
Seen as an engineering challenge, both Macalloy 460 and 1030 bar systems played a pivotal role in the construction of the two 4m-wide bridges, which were later named the Golden Jubilee Bridges.
Using approximately 180 Macalloy 460 Tie Rods on each deck, the tendons were used as deck and backstays, in which the backstays were placed under tension. Specially manufactured tendons threaded M125 were used to create single node points, restraining up to four M64 backstays. In addition, Macalloy 1030 Post-Tensioning Bars were used as trunnion restraints and to hold down bolts.
