Across the Clyde the Clyde Viaduct stands tall. A giant of steel and iron it connects Glasgow’s bustling city centre to its south side. The Clyde Viaduct wasn’t always as imposing as it is today.
The first Clyde Viaduct opened in 1878. Built by Sir William Arrol and Co it was a marvel of engineering. Its 700ft length and 200ft span were impressive. 3000 tons of iron held it together. Rivets were silently driven by hydraulic riveters a revolutionary invention.
But Glasgow grew. The original viaduct couldn’t handle the increased traffic. So a new Clyde Viaduct was constructed between 1904 and 1908. The new structure was 110 ft broad. It carried nine tracks although this varied along its length. Five spans crossed the river three directly over the water.
A fascinating detail is the signal box. Originally located between the old and new viaducts it boasted a state-of-the-art electro-pneumatic signalling system. This advanced technology replaced older signal boxes. It operated until 1961 when the original viaduct was removed. The removal also necessitated the addition of a new portion to the east side.
The old viaduct’s cylindrical piers remain. They stand as silent witnesses to the past. These 15ft diameter cast-iron shafts were sunk deep into bedrock. They are a testament to the enduring legacy of engineering brilliance. Today the Clyde Viaduct still carries trains. It is a crucial part of Glasgow’s transport network. A vital artery carrying people across the Clyde. A beautiful and functional landmark. Look closely. Observe the graceful spans. Feel the weight of history beneath your feet. You are standing on a magnificent structure that has quietly served Glasgow for generations.
