|Route outline (key)|
Like the former N2, it starts on Dorset Street and then takes two different routes around Blessington Street Basin. The two routes combine at Doyle's Corner, where there is a multiplex with the R108, which appears to take priority. After crossing Cross Gun Bridge, the two roads split at Hart's Corner.
At Glasnevin Cemetery, it opens out to a dual carriageway, which bypasses Finglas Village, including a non-primary Grade Separated Junction.
