A white settlement named after Stuart was started ten years later with the construction of a repeater station on the Australian Overland Telegraph Line (OTL), which linked Adelaide to Darwin and Great Britain. The OTL was completed in 1872. It traced Stuart's route and opened up the interior for permanent settlement. The Alice Springs Telegraph Station was sited near what was thought to be a permanent waterhole in the normally dry Todd River, named Alice Springs by W.W. Mills after the wife of the Superintendent of Telegraphs and Postmaster General of South Australia, Sir Charles Todd, who was the driving force for constructing the OTL. The nearby settlement of Stuart was renamed as Alice Springs on 31 August 1933. The Todd River and its tributary the Charles River, which meet near the telegraph station, were named after Sir Charles.
