The M5 Legacy Way (formerly Northern Link Tunnel) is a 4.6 kilometres (2.9 mi) long tunnel linking the Western Freeway at Toowong and the Inner City Bypass at Kelvin Grove, Brisbane. The project consisted of two bored tunnels carrying two motorway grade lanes of traffic in each direction. It opened on 25 June 2015 and is the fourth of five components of Brisbane City Council's TransApex Project. The tunnels will be tolled for approximately 45 years. The project was funded through council borrowings, together with a state and federal government contribution.
