Stops serviced by BUZ routes are often identified with the above sign
Bus upgrade zones, commonly abbreviated to BUZ, are a feature of Brisbane's public transport system. The name is given to high-frequency bus routes operated by Transport for Brisbane, the Brisbane City Council agency that operates the city's public bus services for Translink. All BUZ services run at least every fifteen minutes from around 6:00am to 11:30pm seven days a week and at least every ten minutes during peak hours from Monday to Friday.[1][2][3] The Cultural Centre busway station on the South East Busway is the common interchange point for all BUZ services, with the exception of routes 340 and 412.[2]
Nearly all BUZ routes are express which provide quick and frequent access to places along major trunk roads. However, routes 196 and 199 are an exception, in that they are all-stop services between the inner suburbs of Fairfield, West End, New Farm and Teneriffe. Nearly all BUZ routes are radial travelling to or from BrisbaneCBD. However, routes 196 and 199 are again an exception, in that they are cross-town services that pass the CBD.
History
In 2003, route 111 was upgraded to become the first BUZ service.[4] Other BUZ services have been progressively added since.[5][6]
In 2007, BUZ services carried over 346,000 passengers a week, accounting for around 30% of all Brisbane Transport patronage. Route 199 was the busiest BUZ service, carrying over 53,000 passengers per week.[7]
In 2025, route 111 was replaced by Brisbane Metro route M1.[8] The route remained the same.
