The Minister for Rural and Community Development has confirmed that Ballaghaderreen Library will not reopen until late next year.
A temporary library is to be opened in the town as the original library has now been closed for a number of years for essential works.
The closure of the service has led to much criticism locally, with a number of protests held outside Dillon House in the Town over the last number of years.
It's thought the works on the listed building will take up to 32 weeks to complete.
A new temporary Library will now be established in the former Tusla office in Ballaghaderreen, subject to planning permission.
Once the planning application has been submitted for the temporary service, local councillors will discuss and decide on the issue.
Roscommon County Council have confirmed that project will go out to tender before Christmas with a contractor set to be appointed in early 2024.
A mobile library service has also been provided by the local authority over the course of the closure
