$1 billion road and rail tunnel under the Brisbane river under planning. The 5 km North South Bypass Tunnel would link the southeast Freeway at Woolloongabba with the Inner-City Bypass at Bowen Hills. Pre-feasibility study completed in September, 2001. 01/02.The Brisbane City Council proposes to construct the north-south bypass tunnel which is intended to connect the M1 (Pacific motorway) and Ipswich Road to the south with the Inner City Bypass to the north of the Central Business District / Fortitude Valley. The proposed route will generally follow the alignment of Ipswich Road/Main Street at Woolloongabba in the south, cross under the Brisbane River beneath the Story Bridge and the river bank at Kangaroo Point and then proceed through Fortitude Valley and exit at Bowen Hills northeast of the city, where it would connect with the Inner City Bypass. The project, which will consist of twin 4.7 km two-lane tunnels, is part of the implementation of the Transport Plan for Brisbane 2002-2016. Given the length, a TBM is the most likely technology to construct it. The project is in the detailed feasibility stage. More in E-News Weekly 38/2004.
