Building costs soar on Sydney motorway

NEWS

COSTS OF BUILDING a proposed motorway tunnel in Sydney, Australia have risen to almost AU$1.8bn (£713M) following adoption of a £117M package of improvements.

The preferred option for the M4 East tunnel in the city has been extended by almost 1km in response to community pressure and the outcome of studies.

Roads minister Carl Scully said: 'If the government decides to proceed with the project, construction could start in 2007 and the tunnel could be open to traffic in late 2009 or early 2010.'

Another major Sydney road scheme reached a milestone recently when a 100t road header machine tunnelled its way to daylight after 10 months underground. Two roadheaders machines for the £266M Cross City Tunnel were lowered into the same shaft in the middle of the 2.1km route and worked away from one another.
