Southbank has a network of major roads running through it and is often heavily congested with traffic and limited mainly to offstreet multi-storey parking. The West Gate Freeway runs along the south border which has numerous interchanges to Southbank's roads. The main north–south arterials leading into the Melbourne City Centre are Kingsway, Clarendon Street and Queensbridge/Moray Street. Secondary internal main roads include Southbank Boulevard, Sturt Street and Power Street. The main east–west arterials are City Road (east–west) and Normanby Road (which curves south into Whiteman Street). Many smaller roads allow one-way traffic only, to limit congestion.
