Re-opening the old Glebe Island Bridge for a cycleway, walking path and tram that could connect to Balmain is one option being considered to improve transport links to the so-called Bays Precinct in inner Sydney.

The government is also considering a ferry wharf near the White Bay power station, which it has said it wants to turn into a technology hub, dedicated bus lanes on the Anzac Bridge, and possibly a new metro rail line through the area.

These details emerge in a document title "White Bay Power Station: Transport Proposals" prepared in October last year and obtained using freedom of information laws.

That study was prepared to coincide with a tender process the government is running for companies to redevelop the old power station. It is understood technology giant Google is one of a number of companies interested in using the former coal-powered station as a local head office.
