The Boggo Road Busway Project in Woolloongabba in Queensland, Australia, provides a public transport link for people traveling to the Princess Alexandra Hospital, the University of Queensland, and the Boggo Road Urban Village.
This Queensland government project was constructed in three stages. Stage one extends from Ipswich Road to a point just east of the Boggo Road Gaol site, and consists mainly of an at-grade busway with a cut-and-cover undercrossing under the dual gauge, middle road, and suburban railway lines. Stage two consists of approximately 440 meters (1,445 feet) of driven tunnel extending west from the portal immediately east of the historic gaol site and 70 meters (230 feet) of cut-and-cover tunnel immediately east of the Eleanor Schonell Bridge. Stage three, which is known as the first section of the Eastern Busway, extends from Ipswich Road following O’Keefe Street, and after passing under the Pacific Motorway connects to the existing South East Busway.
Sinclair Knight Merz contracted McMillen Jacobs Associates to provide independent review of the preliminary design and detail design of the stage two driven tunnel. In addition to the independent design reviews, the firm sat on the peer review team for the excavation phase of the driven tunnel. The typical profile of this roadheader-excavated driven tunnel is 14 x 6 meters (46 x 20 feet). A sequential excavation method (SEM) was used to mine the tunnel. Ground conditions consist of several geological units — Tingalpa, Brisbane Tuff, conglomerate, and breccia. Primary support ranged from patterned rock bolts with 50 millimeters (2 inches) of shotcrete to a stiffer support system of grouted canopy tubes with 350 millimeters (14 inches) of shotcrete.
The completed busway opened on August 2, 2009, and was renamed the Eastern Busway by the Premier of Queensland at the opening. Buses began running on August 3.
