The portion south of Newry past Slieve Gullion was scrapped on safety grounds in 2020.

Belfast | Lisburn | Craigavon | Portadown | Newry NCR 9 begins at the west side of the Queen Elizabeth II Bridge, where it connects with National cycle routes 93 and 99.

The Belfast to Lisburn section is a slow and winding route along a path that is suitable for road bikes.

It makes an ideal cycle for young and old, and since bicycles can be taken on trains running on the adjacent railway line, you can choose the length of your route easily.

Newry | Dundalk | Drogheda Dublin Work is underway in Dublin on the 1.4km Liffey-Tolka Project (1.4km),[1] linking the city centre with the planned 3.2km Tolka Estuary Greenway via Dublin Port, and the Fingal Coastal Way, a 32km walking and cycling route in Fingal that will run through Newbridge Demesne, Donabate, Rush, Loughshinny, Skerries and Balbriggan.
