A major factor in the recent growth of Bella Vista has been its prime location near the end of the Sydney M2 motorway. It takes half an hour to get from Bella Vista to the CBD. This also puts Bella Vista close to two major north-south transport routes through Sydney, the Cumberland Highway and the Westlink M7.
Buses are the only form of public transport available to Bella Vista residents. The suburb is serviced by private bus companies Hillsbus and Busways. Relatively frequent buses connect Bella Vista with the nearby hubs of Parramatta (bus number T62, T63, T64, T65 and T66), Castle Hill (bus number T70, T62, 715 and 745), Blacktown (bus number T70) and Seven Hills (bus number 714 and 715). There are also peak services available directly to North Sydney (602) and the CBD (bus number 607X, 613X, 614X, 617X, and 618) and Macquarie Park (bus number 628, 740). Many routes use the North-West T-way.
The closest railway station is at Seven Hills. The $360 million North West Rail Link is currently under construction and will be the main public transport line linking residents of north-western Sydney with Epping, Chatswood, North Sydney and Sydney CBD. It would also improve access to Castle Hill Norwest Business Park and Rouse Hill. Construction of the North West Rail Link is due for completion in 2019.
