George the Fifth Bridge had been planned to be built at the foot of Oswald Street in 1914 but war delayed construction for 10 years and it finally opened in 1928.
Although the bridge appears to be a 3 span masonry arch bridge, it is in this respect a fraud. The granite masonry is facing to a 3 span reinforced concrete box girder construction. Each pier is founded on four cylindrical concrete caissons.
These were floated into position and settled onto the river bed on the ebb tide. The caissons were then sunk to their final positions by removing their temporary bottoms and excavating down to a solid foundation beneath the riverbed.
