Butler's Bridge is one of ten projects across the Grey electorate to receive more than $9.5 million in funding from the federal government.
The bridge is located at about 10 kilometres south of Port Pirie along Old Broughton Road on crossing the Broughton River.
A structural report on the bridge states the year of construction was 1945, which makes the bridge about 75 years old.
The funding comes from Round 5 of the Bridges Renewal Program (BRP) and Round 7 of the Heavy Vehicle Safety and Productivity Program (HVSPP).
Grey MP Rowan Ramsey said the timing could not be better to see funding flow into regional areas to deliver better and safer bridges and freight roads in Grey.
"This includes replacing Butler's Bridge south of Port Pirie with a new concrete bridge, under the Bridges Renewal Program at a cost of $247,000," he said.
"This funding will allow communities right across the country to fast-track their highest-priority infrastructure projects, providing a much-needed boost to local jobs and the economy.
"The federal government is committed to maintaining, repairing and upgrading local and regional roads to facilitate the movement of freight, to key freight hubs and state roads.
"Other bridges to receive funding in this round of the program in Grey include the Andrews Road bridge, Wasleys Bridge and two bridges near Marrabel which will receive $2.5 million to widen and strengthen the existing structures.
"Road upgrades to receive funding include College Road near Roseworthy, Oates, Hatcher and Wilkinson Roads near Lewiston, Gardner Street and Fowler Terrace widening at Price, the construction of a round-about near two Wells, Petersburg Road upgrade in the Mid North near Peterborough and one new and three upgrades to rest areas on Stuart Highway.
"Every single local job we support in Grey by investing in infrastructure projects means one less worry for another Australian and their family, reliable work on the books for local construction companies and more cash flowing through local businesses and communities doing it tough."
Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development Michael McCormack said these latest rounds would support 350 projects across the nation.
