English: Brisbane Metro is a planned high-frequency bus rapid transit system that will service Brisbane, Australia. It will consist of two routes that will run through the Brisbane central business district (CBD) every three minutes during peak times (20vph), transporting up to 3,000 passengers per hour in each direction. It will be serviced by 60 electric, bi-articulated buses that can carry 150 passengers, or 170 passengers in 'event' mode. The system will largely use Brisbane's existing busway network infrastructure and stations, but there are a number of smaller infrastructure upgrades being built as part of the project. These include a new short tunnel underneath Adelaide Street in the CBD, an upgrade to the Cultural Centre bus station, the removal of car traffic from Victoria Bridge, and various streetscape upgrades. The expected total cost of the project is $1.7 billion.
