Thomas Telford 1757 - 1834

Timeline 1757    Timeline 1834

Thomas Telford  was responsible for the early 19th century improvements to the main line canal at Birmingham. Having surveyed the original Brindley contour canal across the Birmingham Plateau he declared it "little better than a crooked ditch" and set about carving a straight line across the route. The result was the largest  earthwork in the world at the time - a little over 70 feet deep and a mile long - now known as the Galton Valley.  It was crossed by the magnificent Galton Bridge, at the time the longest single span bridge in the world. Among his other improvements to the canal system were the Engine Arm feeder canal that crosses the new line and carries water supplies to the old main line across the dramatic, cast-iron Engine Arm aqueduct, a scheduled ancient monument.

Menai BridgeTelford is also known for his audacious improvements to the old Roman road of Watling Street (the A5) that led from London to Wales. His engineering feats include the masterpiece of the Menai Bridge, a suspension bridge that carries the road across the Menai Strait and onto Anglesey to open up the western port of Holyhead. The Menai Bridge was built between 1818 and 1826 at a height of 153 feet, a length of 1388 feet and a main span of 580 feet.




Waterloo Bridge
Another of his A5 works is the magnificent Waterloo Bridge over the River Conwy at Betwys-y-Coed inscribed:"This arch was constructed in the same year the Battle of Waterloo was fought. 1815"
