This was later reverted and today the Circular Quay to King Street section is one-way throughout in a southerly direction.

[4][5][6] The Circular Quay to Central station line was an important part of the Sydney tram network.

It was an extremely busy service for passengers transferring from suburban trains, particularly prior to the opening of the City Circle underground railway line in 1926.

The line closed on 27 September 1957 with four tram services replaced with buses and three others diverted to operate via Elizabeth Street.

[7][8] The line made use of the sandstone viaduct onto the colonnade above Eddy Avenue at Central station, which since 1997 has formed part of the Inner West Light Rail.
