The state government has now spent $54 million on two pedestrian footbridges within several hundred metres of each other near the Sydney Cricket Ground at Moore Park.

Almost five years after opening the $38 million Albert "Tibby" Cotter footbridge, it has emerged that another pedestrian bridge over Anzac Parade has cost $16 million to build.

The bill for the new bridge – named after a World War I surgeon – has been included in the $2.9 billion cost to taxpayers of Sydney's new light rail line from Circular Quay to the eastern suburbs.

While the "Tibby" Cotter walkway is used by a small percentage of visitors to Moore Park, the Doctor Agnes Bennett Bridge is expected to better patronised because it links a stop on the light rail line to Sydney Boys High and Sydney Girls High, government selective schools on the opposite side of Anzac Parade.
