M5 WestConnex motorway : relieving traffic congestion in Sydney
The major WestConnex infrastructure project in New South Wales is designed to smooth traffic flow in the outskirts of Sydney. The M5 motorway, which is currently congested because it serves both the city and the airport, will be given two additional lanes in each direction to double its capacity.
As part of this project, Menard carried out a variety of ground consolidation works, installing a 15,000 sq. metre cut-off wall to a depth of 20 metres, carrying out jet compaction (Rapid Impact Compaction method) and installing 1,500 metres of 750 mm CFA piles and Controlled Modulus Columns over 21,500 linear metres. The M5 is scheduled to re-open in early 2020.
