Provided road, tunnel, bridge and drainage design
SMEC provided road, tunnel, bridge and drainage design; environmental management; community consultation; Environmental Impact Assessments (EIAs); options development and analysis; and documentation and construction management.
SMEC successfully delivered a new seven kilometre long motorway between Currumbin in Queensland and Tweed Heads in New South Wales. Construction was undertaken by the PacificLink Alliance between April 2006 and June 2008 and involved the construction of a four-lane restricted access motorway with a central median to separate north and south traffic flows at a posted speed of 100 km/h. The median was designed to allow for future upgrading of the road to six lanes. The road corridor ranges in width from 60 metres to 90 metres with additional land required at interchanges. The design objective was to maintain the required safety standards and minimise impacts on environmentally sensitive areas.
Significantly reducing traffic times
The project improved traffic flow through the existing intersection at Tugun, significantly reducing travel times for commuters.
