The Darlington Project – designing a modern marvel

The Darlington Project is a $620 million road infrastructure upgrade which forms part of the long-term vision of a North-South Corridor for Adelaide. Darlington contains the busiest road segment (Main South Road~73,000vpd) and busiest at-grade intersection (Main South Road and Sturt Road ~98,000vpd) in South Australia. The project is grade separating five existing signalised intersections across a 2km stretch of Man South Road with eight road bridges being built. The project runs through a precinct which contains the second largest hospital in SA, the second largest University in SA as well as the largest shopping centre in SA close by. The scheme has to contend with extremely complex movements with two roads feeding and receiving traffic at either end, causing traffic movements to be incredibly complex and dynamic and multiple peaks within peak periods due to differing traffic movements. The scheme currently being built is not the scheme from tender time. Subsequent to the tender, traffic volumes were updated which required the scheme to be updated to accommodate the significant increase in traffic forecast to move through or travelling to the precinct in the peaks. This paper will discuss the development of the scheme, the principles ultimately adopted, accounting for the complexity of movements in a safe and sensible manner and the challenges in trying to meet the project objectives; all the while knowing that construction in the incredibly constrained area would play a significant role in ensuring the traffic does not suffer catastrophic delays during construction. During the development of the scheme, issues surrounding the consistency between assessment packages (Sidra/HCM/Aimsim) caused considerable time and effort to be required to reconcile differences and provide the best possible advice.
