|Route outline (key)|
The N81 is a cross-country route running southwest from Dublin via Blessington and Tullow to the N80 at Closh Cross between Carlow and Enniscorthy. Today, however, most traffic between the capital and County Carlow is more likely to take the vastly improved N7 / M7 / M9 route, which runs in roughly the same direction.
The N81 is the only national road emanating from Dublin that is of national secondary rather than national primary status. The first 4-km-long section of the route from its present starting-point of Junction 11 of the M50 – made up of Tallaght Road and Bypass – is, nevertheless, an important outer-suburban dual-carriageway corridor.
