The Legacy Way expressway is approximately 7 km long, including one 4.6 km long twin-tube tunnel connecting the Western Freeway with the Inner City Bypass. The Legacy Way traffic forecast is 34,200 vehicles on an average weekday rising to 50,800 in 2026.
Brisbane City Council (BCC) awarded the Legacy Way project to Transcity JV in December 2010. Transcity JV is responsible for the design, construction, operation and maintenance of the Legacy Way project for 10 years. Transcity JV includes Acciona Infrastructures S.A. of Spain (40%), BMD Constructions Pty Ltd. of Australia (30%) and Ghella S.p.A. of Italy (30%).
The project includes :
• two separate parallel road tunnels, one for the eastbound traffic and one for the westbound traffic, each one with two lane carriageways and connected by cross passages every 120mwithout any lay-by or breakdown bay;
• tunnel portals on the Western Freeway at Toowong and on the Inner City Bypass at Kelvin Grove;
• tunnel management system, fire safety, mechanical and electrical systems, ventilation systems;
• adaptations of existing roads to connect the tunnels to the existing network;
• a free flow electronic tolling system (not part of the contract).
Under the contract signed on 21 June 2013, Egis Road Operation Australia is responsible for the operation and maintenance works of the Legacy Way for 10 years as the sole subcontractor of Transcity JV.
This new success consolidates Egis’ position both in Australia and in tunnel operation and maintenance. Egis currently operates 50 tunnels worldwide for a total length of 47 km.
