R186 road (Ireland)

The R186 is a regional road in Ireland. It is located in County Mayo and County Galway. The road connects the town of Claremorris to the N84 road at Shrule.

The R186 is approximately 20 kilometers (12 miles) in length. It travels in a generally northwest to southeast direction. Starting from Claremorris, it traverses primarily rural landscapes. The road is a single carriageway for its entire length, typically featuring narrow lanes and occasional bends.

The route serves local traffic, connecting smaller villages and providing access to agricultural land. Its primary function is to facilitate movement between Claremorris and the more major N84 route which leads towards Galway. There are no major towns located directly along the R186, contributing to its predominantly rural character. Signage along the route uses the standard Irish road numbering system, indicating the road's classification as a regional road.
