The route connecting Galway with Sligo and the northwest is known as the N17, memorably recorded in the title of a song by late 1980s/early 1990s Irish band The Saw Doctors. It originally started in the centre of Galway city at the intersection of Tuam Road and the N6 Inner Galway Bypass. In September 2017, it was replaced with a motorway to the east, originating in the mega interchange of the M6, M18 and M17, west of Athenry, and terminating west of the small town of Tuam.

A very poor quality section of route follows, as the road negotiates bogs, fields and hills. South of Claremorris, an old good quality grade separated single carriageway road takes the route further past Knock, apparently the scene of an apparition of the Virgin Mary in 1879. North of here, the route is very poor the whole way to Collooney. It passes Ireland West Airport Knock, also known as Knock International Airport, the N5 at Charlestown, and the town of Tobercurry (pronounced Tub 'r' curry), which sounds like a dish of Indian takeaway.

The whole route from the end of the motorway at Tuam to the far end at Collooney will eventually be replaced with dual carriageway, though no end date for this has been set.
