History

A number of upgrade projects were planned for the N17, along with the N18 and N20. Before the 2017 upgrade, the Southern Section N17 was the state's busiest single-carriageway inter-urban road with over 25,000 vehicles using the road at Claregalway daily of which over 20,000 travel on the Claregalway-Galway section south of Claregalway.

In April 2014, this project was given the go-ahead by the Government and was opened to the public in September 2017, many months ahead of schedule.

The motorway is not tolled.
