The M17/M18 Gort to Tuam PPP Scheme forms part of the Atlantic corridor outlined under Transport 21 (Transport 21 is an Irish infrastructure plan). The scheme involved the design and construction of a new road to replace the existing N17 and N18 between Gort and Tuam in County Galway in the West of Ireland.

The 53 km motorway standard road commences at Gort and terminates at the Kilmore Roundabout, just south of Tuam. From Tuam the road is a 4.2 km Type 2 dual carriageway which bypasses the town and joins the existing N17 at Mountpotter.
