Causey Arch
From Wikipedia, the free encyclopedia
The
Causey Arch is a bridge near
Stanley in
County Durham, northern England. It is the oldest surviving single-arch railway bridge in the world.
It was built in 1725-26 by stonemason Ralph Wood, funded by a conglomeration of coal-owners known as the "'
Grand Allies'" (founded by Colonel Liddell and the Hon. Charles Montague) at a cost of £12,000. Two tracks crossed the Arch: one (the
main way) to take coal to the
River Tyne, and the other (the
bye way) for the returning the empty
wagons. Over nine hundred
horse-drawn wagons crossed the arch each day using the
Tanfield Railway.
At the time the bridge was completed in 1726, it was the longest
single span bridge in the country with an arch span of 31 m, a record it
held for thirty years until 1756 when a bridge was built in
Pontypridd, Wales.
An inscription on a
sundial at the site reads "
Ra. Wood, mason, 1727". Use of the Arch declined when
Tanfield Colliery was destroyed by fire in 1739.
The Arch was restored and reinforced in the 1980s. There are a series of scenic public paths around the area and the Causey
Burn which runs underneath it. The quarry near the bridge is a popular spot for local
rock climbers.
Causey Burn itself flows into
Beamish Burn which then flows into the
River Team eventually
discharging into the
River Tyne.
