The Ballochmyle Viaduct is a railway bridge between the Scottish towns of Mauchline and Catrine in the East Ayrshire Council Area . In 1971 the building was included in the Scottish monument lists, initially in monument category B. The upgrade to the highest category A took place in 1989. Not far from the bridge are the rock carvings of Ballochmyle .
description
As an engineer, John Miller from Glasgow is responsible for the construction, with the work being carried out by Ross & Mitchell . The foundation stone of the Ballochmyle Viaduct was laid on September 5, 1846 and construction was completed on August 9, 1848. The commissioning Glasgow, Paisley, Kilmarnock and Ayr Railway opened the route to traffic in 1850. Today the bridge runs the Glasgow – Carlisle railway between Auchinleck and Mauchline over the River Ayr .
The stone arch bridge spans the valley with seven arches , said central sheet having a span of 55.2 m (181 ft ) on both sides of three sheets having smaller inner diameters of 15.2 m (50 ft) is framed. The masonry is made of red sandstone. A harder rock from a quarry near Dundee was used to surround the central arch alone .
The main arch has a headroom of 50.0 m (164 ft) above the Ayr river bed. At the time of its completion it was arguably the largest masonry arch of a railway bridge in the world and still has this rank in Great Britain.
Because of its height, it is also considered by some to be larger than the Grosvenor Bridge on the approach to Chester , which with its segmental arch has a significantly longer span of 61 m (200 ft), but a lower height.
