The $354 million Regency Road to Pym Street project is expected to open to traffic in late April 2021, months ahead of schedule.
Savings of between $20 to $40 million are also expected to be achieved on the project.
Some of the final works including landscaping, ITS commissioning and final asphalting are also on track to be completed by late 2021, instead of early 2022.
Upon completion crews will have built a new 1.8 kilometre section of non-stop motorway along South Road, connecting the South Road Superway to the Torrens Road to River Torrens project. A shared path overpass will also be built spanning 57 metres above the North-South Motorway and South Road surface roads.
This week the girder segments were delivered 600 kilometres, from Bowhill to Adelaide. Weighing 95 tonnes the overpass is one of the largest volumetric loads to ever move through South Australia.
Bowhill Engineering, a local company, built the girder segments as well as the temporary steel trestles on which the segments were built.
The overpass is set to be lifted into position on February 20, 2021.
Over its construction period the Regency to Pym project has employed around 210 people each year.
Federal Minister for Communications, Urban Infrastructure, Cities and the Arts, the Hon Paul Fletcher MP, said the project will deliver travel time savings of up to eight minutes during peak periods and 4.5 minutes on average for around 53,000 motorists on South Road from Regency Road to Pym Street.
“For locals travelling along this route in peak periods day in and day out, eight minutes off their commute adds up to around two whole days each year,” Fletcher said.
“Even more importantly, this project is improving the safety of this popular North-South corridor, reducing the risk of crashes to provide greater peace of mind to locals and visitors alike.”
South Australian Minister for Infrastructure and Transport, the Hon Corey Wingard MP, said the R2P project is an example of excellent engineering and delivery.
“With savings expected between $20 million and $40 million on this project, we’re looking at opportunities to redirect that money to other priority projects across the state,” Wingard said.
“It’s fantastic to be able to support local, family-owned businesses though our major infrastructure projects.”
