The Iron Bridge
The Severn gorge is rich in raw materials, with good coastal access, and
was destined to become an important industrial area once the production
of iron using coke, rather than expensive charcoal, had been developed.
By the mid 18th century industry was thriving, but crossing the river could often be slow and problematic
dependent on the depth and flow of the river. The proposal for a
bridge was only a matter of time, and Abraham Darby III was commissioned
to build it. Contrary to popular belief, the 'Iron Bridge' was designed
by Thomas Pritchard, who enlisted the help of John Wilkinson, a keen iron
enthusiast. In 1775 he proposed the construction of a single span bridge with no river
piers, to eliminate any obstructions to river traffic, at an estimated
cost of £3,200.
Work commenced on the bridge in November 1777, but tragically Thomas Pritchard died in the
same year, never to see his design come to fruition. This bridge
would be the first in the world to use cast iron in its construction. It
is not known for certain where the iron was cast, and subsequently
how it was transported to the site in the deep gorge, but it must have
been a considerable feat to have raised these huge structures. Darby,
rather rashly, agreed to cover any additional costs incurred over the
original estimate. Because of this, he was to remain in debt for
the rest of his life, as the bridge's final cost was well over £6,000.
Charging its first toll, the completed Iron Bridge opened on New Years Day
1781, but only three years later cracks had started to appear in the
ironwork, caused by movement in the gorge. In 1802 the masonry
abutments were removed and replaced by timber, which stood for a further
19 years until the two cast iron arches, seen today, superseded them.
Demolition of the bridge was considered in 1926 due to continued concerns over its stability,
but it survived. However, in 1934 it was closed to vehicular
traffic, and listed as an historical monument. Tolls ceased in
1950 when the ownership passed to Shropshire County Council. During
the 1970s the bridge underwent a considerable restoration programme
which ensured its future stability. Today, the bridge is the
central focus of the Iron Bridge Gorge Museum, which was created to
preserve the industrial heritage of the area. Attractions include
the Museum of the river, and visitor centre, Museum of iron, Darby
Furness and Elton gallery, Blists Hill open air museum, Coalport china museum,
and Jackfield tile museum. For anyone interested in our industrial heritage, this living museum should be an absolute must,
but allow plenty of time because the museums are spread over several miles. |
