Shuttle expressway favours steel flexibility
Adelaide’s new 22km Southern Expressway will operate one-way only and will carry north-bound morning traffic towards Adelaide and south-bound evening traffic out of Adelaide in an efficient and free-flowing manner.
Construction will be carried out over a number of stages. Stage One is complete and stretches 6km between Bedford Park and Reynella and will eventually become the eastern side of a dual carriageway. Its design had to consider both initial requirements for reversible traffic flow and the final requirements for future two-way traffic flow. The two sets of conditions led to some unusual bridging criteria requiring specific design solutions that would suit both expressway configurations.
