The Brisbane River has created a barrier to some road transport routes. In total there are nine road bridges and one road tunnel, mostly concentrated in the inner city area. This has intensified the need for transport routes to focus on the inner city. One more cross-river tunnel is planned (East-West Link) as part of the TransApex plan.
Brisbane's road system was planned around large, spacious suburban areas. Dense suburbs now rely on several main road corridors that split through and between these areas and provide the only link to the CBD and other areas of Brisbane. Logan Road, Moggill Road, Old Cleveland Road and Gympie Road are but a few of these multi-lane corridors that come out of the CBD and snake through the suburbs.
Bypasses such as the Inner City Bypass, Airport Link and Clem Jones Tunnel are intended to help to circulate traffic away from the inner-city areas and main roads via limited-access roads above the ground, and tunnels below that have higher speed limits and exits to particular suburbs.
Existing high speed cross-suburban motorways such as the Western Freeway, Centenary Freeway, Pacific Motorway and Gateway Motorway provide alternative routes to main roads and connect up to main highways and other arterial roads. The TransApex plan tunnels, Airport Link tunnel and Clem Jones Tunnel, Legacy Way tunnel and East-West Link tunnel are designed to link all the various motorways in Brisbane together. Only East-West link is yet to commence planning or construction.
In total, the twisting Brisbane River is crossed by nine road bridges, one road tunnel, three railway bridges, three dedicated cyclist/pedestrian bridges and one dedicated bus/cycle/pedestrian bridge. Route signage is achieved by means of a system of Metroads, consisting of the most important arterial roads in metropolitan Brisbane including most motorways, and less important State Routes; however, in recent years, the Metroads are being superseded by an alphanumeric numbering system. Multiple freeways connect Brisbane to other cities, including the Pacific Motorway, the Bruce Highway and the Ipswich Motorway, all of which are part of the National Highway System. Brisbane is approximately 1000 km away from Sydney, the closest major capital city.
An upgrade to Brisbane's traffic lights system began in April 2011. The old system was called Brisbane Linked Intersection Signal System (BLISS) and required a controller to trigger traffic lights to relieve congestion. The new system called Sydney Coordinated Adaptive Traffic System (SCATS) is used in every other Australian capital city and is expected to cost much less to maintain. All 850 sets of Brisbane City Council signal boxes require upgrades.
Six major roads and bridges in Brisbane are tolled, with all of them using free-flow tolling technology.

Famous quotes containing the word network:
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
“Parents need all the help they can get. The strongest as well as the most fragile family requires a vital network of social supports.”
—Bernice Weissbourd (20th century)
“A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
—Jacques Barzun (b. 1907)
