The sod will also be turned on the cycleway bridge over the River Shannon.
The new Athlone greenway will be officially opened next month.
Minister of State for Tourism, Hildegarde Naughton will visit the town for the ceremony on Monday October 4th, and also turn the sod on the River Shannon cycleway bridge project.
