 It forms part of the A24.The road, as currently laid outm dates from the first decades of the nineteenth century when a bridge was built connecting Newtownbreda village to Belfast.This route was known more commonly as the New Ballynafeigh Road before eventually taking on the name of Ormeau House, the Marquess of Donegall's residence, which it passed by (and which in turn took its name from the French word "ormeau", meaning "young elm").
