The motor vehicle is the main form of transport in Ballarat. A network of state highways radiate from Ballarat and the Western Freeway (A8) dual carriageway bypasses the central city to the north of the urban area, providing a direct road connection to Melbourne (approximately 90 minutes), westward to Ararat (approximately 75 minutes) and Horsham. Five freeway interchanges service the urban area, East Ballarat (half diamond) interchange at Victoria Street (C805); Brown Hill interchange (full diamond) at Daylesford-Ballarat Road (C292), Creswick Road interchange (full diamond) at Wendouree (A300); the Mount Rowan interchange (half diamond) at Gillies Road, Wendouree (C307) and the Mitchell Park interchange (full diamond) at Howe Street (C287). The Midland Highway is a dual carriageway which runs north along Creswick Road to the Western Freeway interchange but becomes a single carriageway north of Ballarat to Creswick (approximately 25 minutes) and runs south as the dual carriageway of Skipton Road to Magpie before becoming a single carriageway to Geelong (approximately 87 minutes). The Glenelg Highway connects directly to Mount Gambier and the Sunraysia Highway west of Ballarat which connects directly to Mildura. Sturt Street and Victoria Street, both dual carriageways carry the bulk of the east-west CBD traffic, while Mair Street is planned to become a four lane dual carriageway to relieve pressure on these main streets. Other dual carriageway main roads in the west include Howitt Street and Gillies Street. The busiest roads by far are located in the west and south at Albert Street in Redan, Sturt Street in Newington and Gillies Street in Lake Gardens which carry 22,400, 22,000 and 21,500 vehicles per day respectively and all have 4 traffic lanes.
