I haven't seen a thread on the topic but there is public consultation taking place for 5 different proposed routes for Galway - Athlone.

4 routes go through Athenry. The 5th goes via the Burren and to Galway along the coast via Kinvara and Clarinbridge.
Any new greenway is good new but personally I'd love the idea of safely cycling into Galway city and out towards the Burren.
