The bridge linking Langtree Park to St Helens town centre will be renamed in honour of Steve Prescott.
The Saints legend died last year, at the age of 39, after battling a rare form stomach cancer.
Council Leader Barrie Grunewald said: “Steve was a first class ambassador not only for rugby but for the town. As well as being a legend of the game he is also honoured for his tireless fund raising for his Steve Prescott Foundation.
“By naming the bridge after him is our tribute to one of the greats of St. Helens and a most well deserved honour, all the more so that the bridge links the town Steve loved so much to his beloved club."
Steve, who played for St Helens, Hull and Wakefield and for England and Ireland, was diagnosed with pseudomyxoma peritonei in 2006.
The full-back was given only months to live but battled the disease and in 2009 was awarded an MBE for his charity work.
He raised hundreds of thousands of pounds for charity through the Steve Prescott Foundation.
Mike Rush said: "It is only fitting that one of St Helens' greatest sons has such an honour bestowed on him and we are delighted that St Helens Council has taken this decision."Steve will be missed by us all and the Club will also make sure he has a fitting legacy at Langtree Park. We will start that process when Saints take on Hull FC in February."
Mike Denning Chairman of the Steve Prescott Foundation added: "This is very fitting for a real life Hero and Sporting icon born here in our town. Steve has inspired so many and has raised awareness of not only the very rare form of cancer which he battled but also the plight of those injured or fallen on hard times in the great game of Rugby League.
