The $38M Bruce Highway Upgrade (Tinana Interchange) Project was awarded to Georgiou in July 2016 as a part of the $8.5B Bruce Highway Upgrade 10 Year Upgrade Program for client Department of Transport and Main Roads (DTMR).

Located 5km southwest of Maryborough QLD and spanning 2.4km, the Bruce Highway Upgrade (Tinana Interchange) Project included:

  • construction of a northbound 2 span off-ramp bridge/overpass structure (including demolition of existing bridge overpass);
  • earthworks to improve alignment geometries, including cuts of up to 12 metres, and fills up to 5 metres from existing road levels;
  • relocation of the Three Mile Road West intersection about 300 metres south of its original location;
  • removal of the southbound off-ramp to Gympie Road and construction of a new southbound off-ramp to Iindah Road;
  • incorporation of a wide centre line treatment to provide greater separation of opposing directions of traffic.

Other features of the project included:

  • Road – earthworks, drainage upgrades, bridge approach works, asphalting,, line marking and signage, landscaping, concrete channelling  and retaining wall construction;
  • Bridge – main overpass structures, piling for bridge foundation, abutment construction, placement of precast girders, in-situ concrete deck, deck wearing surface and bridge barrier construction;
  • Other – public utility plant, road lighting, koala exclusion fencing and fauna underpass, pram ramps and tactile ground surface indicators to assist the visually impaired.

With the project opened to traffic in August 2017, the interchange has improved safety and operational efficiency and supports future growth in the Fraser Coast, as well as a safe passage for local fauna to cross underneath the busy highway without impeding traffic.
