Richmond Road Bridge
The Westlink M7 Motorway, which opened in December 2005, is one of the most ambitious infrastructure projects yet undertaken in Australia.
The 40 kilometre motorway links the M2 at West Baulkham Hills, the M4 at Eastern Creek and the M5 / Hume Highway at Prestons.
Westlink M7 bypasses 48 sets of traffic lights, allowing a journey from south of Liverpool to Pennant Hills in less than 30 minutes. This trip would previously have taken up to an hour longer.
SCI manufactured in excess of 1600 precast prestressed concrete bridge elements to various configurations and geometry over a 16 month contract period. The Richmond Road bridge superstructure was comprised of 1800mm deep Super-T girders spanning 36m and weighing 76 tonnes.
