BusConnects Phase 3 has launched today and will include the implementation of two northside orbital routes from Sunday.
The N4 and the N6, which will see the replacement of the 17A, were originally expected to begin in January but were delayed due to driver shortages.
This third phase will be in effect from Sunday May 29, with the N6 route being operated by Go-Ahead Ireland and the route will link Finglas and Howth Junction, via Beaumont Hospital.
