Re: TODAY IN HISTORY

5th March 1850 - the Britannia Bridge, connecting the North Wales mainland with the island of Anglesey, over the Menai Strait, is opened. The bridge was destroyed by a fire in 1970 and had to be re-built. The bridge was built because, when Ireland became a part of Britain in 1801, many people used the island of Anglesey to travel across the Irish Sea to Ireland whenever they needed to go there.

The original Britannia Bridge.

There are several bridges connecting the North West Wales mainland with the isle of Anglesey over the Menai Strait.
The completion of the Menai Bridge was a boon in easing the journey to the island, particularly for travel to Ireland. However, the rapid rise of rail travel later in the 19th century meant that there was soon a need for trains to cross the Strait. When plans were first being made to build a railway to Holyhead it was proposed that the carriages be taken over the Menai Bridge; the carriages would be uncoupled from the locomotive at one end, then drawn across one by one, using horses, to a waiting locomotive at the other end.
This idea was abandoned and plans were drawn up for a new bridge by Robert Stephenson, son of the locomotive pioneer George Stephenson. He faced the challenge of building a bridge rigid and strong enough to carry a heavy train of many carriages. This was done by making the bridge out of two long iron tubes, rectangular in shape, through which the trains would travel.
When first conceived, the tubular bridge was to have been suspended from cables strung through the openings at the tops of the towers. However, after engineering calculations and tests of the finished tubes it was decided that they were strong enough by themselves to carry the trains.
Like the Menai Bridge, the stonework of the Britannia Bridge was constructed of limestone from Penmon, although sandstone from various places was used internally. The tubes themselves were constructed on the banks of the Strait.
Stephenson faced a much greater challenge in raising the 1,500 ton finished tubes than had Telford with his much lighter chains. He too would float the tube into position. However, the process didn't go as smoothly with the first tube as with the Menai Bridge chains and the giant tube came close to being swept out to sea. Fortune prevailed and it did finally end up in place. Then, very slowly, using hydraulic pumps, the tube was raised into position. Stonework was built up under the ends of the tube as it was lifted; this was to support it if the lifting equipment failed. This was fortunate because one pump did indeed fail, but the tube only fell nine inches.
With the tubes in place the final touches were added. These are the four magnificent limestone lions that guard the entrances to the bridge. They were carved by John Thomas, who had also done stone carving for the Houses of Parliament and Buckingham Palace in London. The lions are almost 4 metres high and sit on plinths of equal height. The bridge was opened on 5 March 1850.
The present day bridge has a much different appearance than the original. This is because it has been reconstructed after a disastrous fire in 1970. A group of teenagers looking for bats in the dark tubes accidentally dropped the burning paper they were using as a torch. This eventually started a ferocious fire through the whole tubular structure that caused so much damage to the tubes that they were in danger of falling into the strait.
