This is the second part of two aerial films of Bennerely Viaduct
This wrought iron lattice work viaduct is 1452 feet long with the rails 60 feet 10 inches above the Erewash River. Most railway viaducts at the time were brick-built but the foundations of the Bennerley Viaduct were subject to a great deal of coal mining subsidence therefore, the lighter wrought iron design was chosen.
The viaduct was built between May 1876 and November 1877 and formed part of the Great Northern Railway Derbyshire Extension which was built in part to exploit the coalfields in Derbyshire and Nottinghamshire.
Bennerley viaduct’s wrought iron construction saved it from demolition. The demolition contractors who tendered for the contract to demolish the viaduct put forward amounts that were considered too high. The reason given for the high cost was that wrought iron structures could not be cut up with an oxy-acetylene torch and would have to be taken apart rivet by rivet.
