 The route then carries on as a single carriageway through the Clogher Valley villages of Augher (A28), Clogher and Fivemiletown.The road crosses the county border into County Fermanagh, and skirts past the villages of Brookeborough, Maguiresbridge (A34), Lisbellaw and Tamlaght on its approach to Enniskillen.These villages were by-passed in the 1960s, and since then the Ballygawley-Enniskillen stretch of the A4 has seen the construction of numerous climbing lanes and overtaking lanes in both directions.
