Originally Loughlinstown was a village on the road from Dublin to Bray in County Wicklow. During the 1960s, one of the earliest stretches of dual carriageway in Ireland was built through the area, leaving the village scattered along the western side of the new road.
For years a large mature chestnut tree was located in the middle of the dual carriageway at its junction with the Wyatville Road. It was known as The Big Tree and was a landmark feature on the road from Dublin to Wicklow. In the 1970s the junction was upgraded and the tree removed. In 2004 the 1960s road was replaced with a new dual carriageway and the junction was replaced with an overbridge.
