The M7 Clem Jones Tunnel (CLEM7), known during its development as the North–South Bypass Tunnel (NSBT), is a A$3.2 billion motorway grade toll road under the Brisbane River, between Woolloongabba and Bowen Hills in Brisbane, Queensland. The tunnel was progressively opened to traffic from late on 15 March 2010 until just after midnight on 16 March 2010. It was completely open by 12:02 am.

The Brisbane River is the longest river in South East Queensland, Australia, and flows through the city of Brisbane, before emptying into Moreton Bay on the Coral Sea. John Oxley, the first European to explore the river, named it after the Governor of New South Wales, Sir Thomas Brisbane in 1823. The penal colony of Moreton Bay later adopted the same name, eventually becoming the present city of Brisbane. The river is a tidal estuary and the water is brackish from its mouth through the majority of the Brisbane metropolitan area westward to the Mount Crosby Weir. The river is wide and navigable throughout the Brisbane metropolitan area.
