The London Road Viaduct is a brick railway viaduct
Viaduct
A viaduct is a bridge composed of several small spans. The term viaduct is derived from the Latin via for road and ducere to lead something. However, the Ancient Romans did not use that term per se; it is a modern derivation from an analogy with aqueduct. Like the Roman aqueducts, many early...

In the 1840s, the land northeast of Brighton station was undeveloped, consisting of fields. It lay in a steep-sided valley running from north to south, created by the River Wellesbourne (by then, reduced to an intermittently flowing, mostly underground winterbourne

Embankment (transportation)

Nevertheless, he planned a route for it, and laid the foundation stone on 29 May 1845. Construction took 10 months: the structure was ready on 28 March 1846, more than two months before the line to Lewes opened. By the 1870s, dense terraced housing

 dropped several bombs on Brighton, five of which landed on the railway. One demolished two arches and one pier at the west end of the viaduct, two arches west of the Preston Road span, leaving the tracks spanning the gap in mid-air. Despite this, a temporary repair allowed trains to start using the viaduct again within 24 hours; in less than a month, the service was back to normal. Until the arches were fully repaired in September 1943, however, a 15 mph (24.1 km/h) speed restriction was enforced and Preston Road could be seen through the gaps between the sleepers

Architecture

The structure is 1200 feet (365.8 m) long, and reaches a maximum height of 67 feet (20.4 m) above the floor of the valley. It consists of 26 semi-circular arches each of 30 feet (9.1 m) with piers of 7 feet (2.1 m) thick at the base and 5 feet (1.5 m) thick at the top, together with one elliptical arch of 50 feet (15.2 m) over a section of the A23 London Road

 called Preston Road. The piers of this arch are 22 feet (6.7 m) thick at the base and 19.5 feet (5.9 m) thick at the top. Each pier contains a jack arch

 with a semi-circular soffitt and invert to reduce the number of bricks required. The piers are thicker on the outside than on the inside because the viaduct is constructed on a sharp curve: trains reach the viaduct almost immediately after leaving the Brighton Main Line, and the line continues to curve away for several hundred metres. Of the 27 arches, 16 have a radius of curvature
