The Princes Highway, Berry to Bomaderry project involves a four-lane upgrade to a 10.5km section of the highway, approximately 60 km south of Wollongong.
The scope encompasses significant civil, structural and road works including 13 bridges (4 standalone and 9 with no separated median), 3 main box culverts, U-turn facilities, intersections, interchanges, a 300m long cutting, major utility relocations, vehicle breakdown bays, a heavy vehicle inspection bay and extensive modifications to local roads.
Traffic management is a crucial component of the construction, with the works being constructed on and around operating roads and adjacent to live traffic.
In September 2020, a weathering steel bridge – an Australian first for road traffic – was opened to the public to form an overpass over the Princes Highway, to connect local roads at Meroo Meadow. The 102 metre long weathering steel structure weighs approximately 352 tonnes. The girders are made from local Australian REDCOR (R) weathering steel.
Once completed, the upgrade will increase road capacity, improve traffic flow, deliver better and more reliable journeys, increase overtaking opportunities, improve safety and allow for the future growth of New South Wales’ south coast.
“I wanted to take the time to write to express SafeWork’s thanks to TfNSW and particularly your delivery partner, the Downer Seymour Whyte Joint Venture (DSWJV). Our thanks comes as the DSWJV team recently donated its time and expertise to benefit some 110 regional businesses at the South Coast Safety Conference. His presentation included the fundamentals and best practice technical advancements in proximity detection / no-go zone detection systems. Importantly, the presentation was delivered from the perspective of a regional project, which is highly valued by the regional businesses attending…”
