The central one in the group of three southwest of Deansgate Station is the high-level iron truss girder viaduct of 1877 built for the Cheshire Lines Committee by the Midland Railway. It's known as Cornbrook Viaduct. The viaduct is a red brick and wrought iron truss girder construction. When it opened in 1877, it carried trains coming from a temporary station to Irlam and Warrington, and Chorlton via a branch line. The temporary station was replaced by Sir John Fowler's Manchester Central Station in 1880, which operated until 1969 and is now used as an exhibition centre (Manchester Central).
