Classon's Bridge, bridge in Ireland

Classon's Bridge is a granite stone crossing that spans the River Dodder and links Milltown with Dartry. The structure features both a vehicle roadway and a pedestrian underpass that allows walkers to cross safely beside the traffic.

John Classon, who owned a mill on the left bank of the River Dodder, built the bridge to serve his business; the mill site is now occupied by The Dropping Well pub. Before its construction in the late 18th century, the only crossings in the area were a ford and a narrow bridge at Milltown that was too narrow for vehicles. The bridge was widened in 1928, and parts of the old structure remain visible underneath.

The bridge takes its name from John Classon, an 18th-century mill owner whose business shaped the area. This connection keeps local history alive for those who walk across and notice the stories tied to the structure.

The bridge carries the Lower Churchtown Road (L3001) over the River Dodder between Milltown and Dartry. A pedestrian underpass lets walkers continue along the riverbank without crossing the roadway. Parts of the older structure remain visible beneath the 1928 widening.

A little upstream from the bridge, a statue of a rhinoceros stands in the middle of the River Dodder. It is easy to miss from the roadway, so look over the parapet towards Milltown to spot it.
