The River Dunkellin is crossed by the M6 at Craughwell as it continues west towards Galway. Outside the city itself, Oranmore is bypassed to the west and north, where the M18 crosses the M6. This dual carriageway bypass brings the route into Galway itself, where it meets the N83 along Bóthar na dTreabh. The Headford Road, Quincentenary Bridge across the River Corrib and Quincentenary Bridge Approach Road bring the N6 through Galway itself to meet the N59 on the western side of the city.
