Legacy Way was designed to reduce congestion on two of Brisbane’s busiest arterial roads and was the last link in Brisbane City Council’s TransApex plan ring road of major infrastructure projects that now provides a system of bypasses and vital river crossings around the city centre. The $1.5 billion tunnel project allows motorists to travel from the Western Freeway at Toowong to the Inner City Bypass at Kelvin Grove in four minutes and avoid seven sets of traffic lights.
The two tunnel excavations were completed in record time – the first 4.26-kilometre tunnel was completed in nine months and 10 days, the second 4.27-kilometre tunnel was completed in six months and nine days. The majority of surface work was completed offline, with reduced impacts on motorists using two of Brisbane’s busiest arterial roads.
Legacy Way received the Infrastructure Partnership Australia Project of the Year award in 2015, International Tunnelling Awards 2013 Major Project of the Year (more than $500 million) and Australian Asphalt Pavement Association 2016 National Outstanding Project Award.
