Meanwhile, as at the census date, compared to the national average, households in the Belconnen district had a marginally higher than average proportion (21.4 per cent) where two or more languages are spoken (national average was 20.4 per cent); and a relatively average proportion (77.0 per cent) where English only was spoken at home (national average was 76.8 per cent). The primary mode of transport within the District is by private vehicle. The District of Belconnen was planned in the 1960s and was guided by a philosophy of reliance on private personal transport and an abundance of roads. Public buses serve the district and a bus interchange that used to exist in the Town Centre, in its place is a bus station that services all suburbs, City/ South Canberra as a way point for passengers exiting the nearby Westfield shopping town at Benjamin Way. Belconnen is well served by a network of near-freeway-quality roads located between suburbs and intersecting the district. The main roads between suburbs are typically landscaped with mounds of earth and vegetation to form 'parkways'. The main roads connecting the district with North Canberra and the city centre are Belconnen Way and Ginninderra Drive. These roads are 6 lane parkways for the majority of their length and run in an east–west direction. Belconnen is situated south of the Barton Highway which leads to Yass, where it connects with the Hume Highway to Sydney and Melbourne. To the south of the district is William Hovell Drive which connects the southern and western suburbs of Belconnen with Parkes Way and the Tuggeranong Parkway which lead to the city centre and Canberra's southern districts respectively. The ACTION bus service which provides public transport throughout Canberra is the only form of regularly scheduled public transport in Belconnen. Services from the various suburbs generally pass through a bus interchange at Belconnen Town Centre from where they continue to Civic and the other town centres to Canberra's south. Some services travel to Gungahlin. There are also express services which connect directly with Tuggeranong. The bus interchange is spread across the Belconnen town centre in three different locations. The previous interchange, which is now one of those locations, was connected by footbridge to large shopping centre and to office buildings occupied by major Government departments. It was an ageing facility which was criticised for being unsafe, particularly at night, and for being dirty and prone to vandalism. For these reasons it was subject to major renovations. The ACT Government plans to construct a busway to connect the Belconnen Town centre with the hospital and CIT precinct in Bruce and the city centre.
