The Military Road is a road through the Wicklow Mountains, running North/South across the spine of the hills. Construction of the road started in 1800 and it was completed in 1809. It was built in the wake of the 1798 rebellion to give British forces access to the Wicklow Hills where many rebels sought refuge
The R115/Military Road starts in Rathfarnham, in County Dublin, rises through the Dublin Mountains (past the Hell Fire Club) and then descends to Glencree at the head of the valley of the Glencree river before rising again to the Sally Gap crossroads. From there it further rises to its highest point below the summit of Tonelagee Mountain. From there it descends to the village of Laragh, near Glendalough.
The R115 terminate at Laragh, at a junction with the R755 and the 'Wicklow Gap' road, the R756. The Military Road continues south past Glenmalure to Aughavannagh in south County Wicklow, but is designated as a local road south of Laragh.
