M3 Inner City Bypass (ICB) is a major motorway standard road in Brisbane, Queensland. The 4.5 kilometres (2.8 mi) bypass is north of the city. Bypassing the Brisbane central business district, it connects Brisbane’s Pacific Motorway and Go Between Bridge at Hale Street to Kingsford Smith Drive, Legacy Way Tunnel, Clem Jones Tunnel, AirportLink Tunnel and Lutwyche Road following the Exhibition railway line for the majority of its length.

The route is marked as the M3 from the western part of the route, to the Horace Street interchange.

The motorway cost $220m to complete and incorporates a total of six lanes, four tunnels, 18 bridges and was the largest infrastructure engineering project undertaken in Queensland for decades. The route also includes a 350-metre-long (1,150 ft) tunnel under the RNA Showgrounds. There is no toll for use of this roadway.

The ICB, built by the Brisbane City Council, is considered one of the most successful road projects in Brisbane, completed well before schedule, on budget, and to date is one of the most used road corridors in the city.

Future interconnectivity

Although not constructed as part of the TransApex project, the ICB is an integral part of the future connection of tunnels and other planned urban motorways within the city. The Inner City Bypass has also been connected to the Airport Link and the Legacy Way tolled tunnels.

The Airport Link was completed in mid-2012[1] and the Legacy Way in late June 2015.
