Grosvenor Bridge
River Dee, Chester
associated engineer
Thomas Harrison
date  1827 - 1834
era  Georgian  |  category  Bridge  |  reference  SJ401655
ICE reference number  HEW 104
A spectacular classically-inspired road bridge with a single masonry span of 200ft, the widest masonry span in the world at the time and still the widest in Britain.
Harrison is said to have designed the bridge in 1802, some 25 years before it was constructed. By 1827 he was over 80 years old and took no part in its building or the development of construction methods for it.
The materials used are Peckforton stone, Scottish granite and Chester red stone. The carriageway is 24ft wide and 42ft above the river. The parapets are 33ft apart.
Harrison moved to Chester in 1793 after a decade spent in Lancaster. Before that he spent seven years in Italy and was much influenced by its architecture.
Contractor: James Trubshaw, with William Cole and Jesse Hartley as supervisors
