Councillors in Peterborough have agreed to spend an additional £1 million retrofitting the London Road terrace into an all-seater stand.
The decision means that the total investment is now in place to redevelop the Peterborough United ground into an all-seater community stadium.
Councillor Marco Cereste, Leader of Peterborough City Council, said: "This is not just a good deal for the football club, this is a good deal for the council, its taxpayers and for Peterborough.
"Once the project is complete we will have a fantastic all-seater community stadium and skills centre which will benefit the football club and the wider city.
The skills centre, which will form part of the new Moy's End stand, will provide vocational training for young people in areas such as electronics and plumbing, as well as apprenticeships and undergraduate and postgraduate courses.
"The agreement with Peterborough United also supports our aim of maintaining a professional footballing presence in the city and ensures that the club is able to play matches at the ground regardless of which league it sits.
The new community stadium will also be a key part of the wider South Bank regeneration project, which includes the nearby Vista housing development. "I look forward to work to starting on site in the autumn."
