Bridge over the Tyne.
c.1870 First Redheugh Bridge opened. This was a most unusual bridge, designed by Thomas Bouch to carry pedestrians and horse-drawn traffic. Iron lattice girders were joined to give a continuous length of 743 ft. The top member of the girders was tubular, and doubled as gas mains. The bottom members were U-shaped, and each carried a 12" water main. There were three towers, each having four 3 ft diameter cast iron columns to support the deck, and these stood on four 12 ft diameter caissons. Rising from these towers were pairs of lattice towers, to the top of which were attached diagonal tie bars giving support to the deck at one third of the length of each span.[1]
1897 Construction of replacement bridge started; engineers Sandemann and Moncrieff; built by Arrol and Co[2]
