Galway city council is cutting the speed limit on multiple stretches of the Headford Road and Bothar na dTreabh for the coming year.
The speed limit will be reduced to 50km/hr to allow for road improvement works which get underway next week on August 12 and are expected to take 12 months to complete.
Some areas will only see minor changes, with the speed limit on the Headford road from Ballinfoile out towards Ballindooley only dropping by 10km/hr per hour.
However motorists are advised that parts of the N6 from Coolagh Roundabout to the Briarhill Junction, and from there to the Ballybane Junction, will see the limit cut in half, down from 100km/hr.
The city council has made this order under section 10 of the Road Traffic Act, 2004 for the N84 Headford Road 2019 and N6 Bothar na dTreabh Road Improvement Works.
The full area of road affected and the changes being made to the local speed limits are:
