First elevated railway into London and the longest run of arches
The London Bridge & Greenwich Railway Viaduct, built between 1834 and 1836, consists of a series of nineteen brick railway viaducts linked by road bridges between London Bridge railway station and Deptford Creek, which form a single structure 5.6 km (3.45 miles) in length. Carrying the former London & Greenwich Railway line, the viaduct comprises 851 semi-circular arches and 27 skew arches or road bridges.
It is one of the world's oldest railway viaducts and the earliest example of an elevated railway line. It is also the longest run of arches in Britain.
The original viaduct was subsequently widened for a 3.1 km (1.95 miles) stretch on the southern side between Corbett's Lane and London Bridge on the south side to accommodate the trains of the London and Croydon Railway and London and Brighton Railway, in 1842; and also for 4.3 km (2.65 miles) on the north side to accommodate the South Eastern Railway main line in 1850.
