Between 2010 and 2012, CIMIC subsidiary Thiess worked as part of a joint venture to significantly improve transport rail services to residents of Adelaide’s southern suburbs. The 5.7-kilometer Seaford Rail Extension will save them about ten minutes on their way to the city. In addition to rail lines, stations, and park-and-ride facilities, the project also included a bus station, three road bridges, and a 1.2-kilometer-long bridge over the Onkaparinga Valley. The long span technique helped Thiess minimize the construction footprint on the southern nature reserve.
