Laigh Milton Viaduct

The Laigh Milton Viaduct is a stone railway bridge with four arches that crosses the River Irvine. The structure uses segmental arches made from local sandstone and displays sturdy engineering from the 19th century.

The viaduct was built between 1809 and 1811 under engineer William Jessop and was part of Scotland's first public railway. This line connected the town of Kilmarnock with the port of Troon.

The structure shows early Scottish engineering skill and holds protected status for its architectural importance.

You can reach the viaduct via a footpath near Laigh Milton Mill, where information boards explain the technical details. The site is best accessed during dry weather and requires comfortable walking shoes.

During a 1995 restoration, an internal steel framework was installed to support the original stone structure while keeping its historical look intact. This hidden reinforcement allowed the aging bridge to be secured for future generations.
