A £69 million council bid will go to the Scottish Government for the next phase of the Dumfries Learning Town Project.
Councillors will be told at a meeting on Thursday that more than £46 million is needed to replace Dumfries High School.
And a further £22.7 million needs to be spent on refurbishing Dumfries Academy and relocating Loreburn Primary into the Minerva building at the secondary school.
Education committee chairman Jeff Leaver said: “Our council is committed to progressing phase two of Dumfries Learning Town.
“The next round of funding is now available, and we must move swiftly to submit a bid and include it in our capital programme.”
The refurbishment element of the academy works includes solutions to the poor accommodation for music and PE on the campus and will address other backlog maintenance issues.
Members will be asked to give the go-ahead for council boss Gavin Stevenson to submit a bid to Holyrood for the money next month.
Further details on the project will be revealed if the application is successful.
The first phase of the project saw the creation of the North West Community Campus, The Bridge learning hub and an overhaul of St Joseph’s College.
It was revealed last November that plans for phase two were being drastically scaled back due to financial constraints.
Instead of two new campuses, Dumfries High School would be replaced and Dumfries Academy, Laurieknowe and Noblehill primaries would be refurbished.
But the “priority” plans were put on hold due to the coronavirus crisis.
Education committee vice chairwoman, Ros Surtees, said: “Every pupil deserves the best possible education facilities.
“We must now move quickly to further develop our region’s school estate.”
