Connacht GAA are hoping to open the new €3 million Air Dome at the Centre of Excellence in Bekan by December.
Work is due to get underway on the facility in early July.
The dome will measure 150 metres and 100 metres and will be 26 metres at its highest point.
The venue, which will seat in excess of 600 people, will host matches during poor weather conditions, as well as holding conferences and exhibitions.
€2.1 million has already been allocated to the project by the Department of Community & Rural Development,
