Percy AllenPercy Allan (1861-1930) was a revered civil engineer who worked for the NSW Department of Public Works. He was appointed engineer-in-charge of bridge design in 1896. When he retired in 1927, his department had designed 583 bridges under his supervision. He designed the Pyrmont Bridge (opened 1902) and the Glebe Island Bridge (opened 1903) and both structures are regarded as monuments to his skill.
Glebe has a further connection with this famous bridge designer. The canal crossing from Jubilee to Bicentennial Parks is a bridge type known as the Allan Truss Bridge. The current bridge is a replica of the original.
