Great Western Highway upgrade: Hartley Valley to Forty Bends
Seymour Whyte upgraded the Great Western Highway at Forty Bends and delivered safety improvements at Hartley Valley between River Lett Hill and Forty Bends. The safety upgrade project involved reconstruction, realignment and widening approximately 12 km of the Great Western Highway to improve safety and traffic flow on this busy Sydney to central west NSW commuter, freight and tourist route. The project included batter stabilisation work, upgrading underground utility services, as well as the construction of retaining walls, fauna crossings, and an eastbound downhill overtaking lane on River Lett Hill. Further improvements provided more consistent intersection treatments on the Great Western Highway and an improved road with wider shoulders. Seymour Whyte delivered the project in stages to provide improvements while reducing the overall impact of construction on the community.
