The additional works involve widening the motorway from four to six lanes from Mt Gravatt-Capalaba Road to Miles Platting Road.Abigroup national operations director John Kirkwood said the new contract was a vote of confidence from the Queensland government and Queensland Motorways on the joint venture’s work on the Gateway upgrade project.“Thanks to production efficiencies and innovations made by the project team, the new Gateway Bridge will be opened in May, six months ahead of schedule, and the motorway works are being completed in a timely and cost-efficient manner,” Kirkwood said. Leighton Contractors managing director Peter McMorrow said the venture was proud to continue its partnership with Queensland Motorways and the state government, delivering much-needed road infrastructure improvements.Work on the 4km Gateway upgrade project extension will commence immediately and is expected to be completed by mid-2011.
