Tunnelling is proceeding with extreme care at the Boggo Road Busway tunnel in South Brisbane.  In early March the tunnel had advanced around 100m and was located directly beneath the heritage listed gaol built back in 1903.  Canopy tubes and lattice girders are being utilised to manage ground settlement with the tunnel cover to surface getting down to five metres (see photo).

When completed, the 430m long tunnel will connect the South East busway to the recently opened Eleanor Schonell Bridge. 

Tunnelling commenced in September 2007 using a Voest Alpine AM105 roadheader.  The work is being undertaken in an alliance which includes Queensland Transport, Thiess, SKM and United Group.
