  Britannia Bridge - Wikipedia, the free encyclopedia
Britannia Bridge (Pont Britannia) is a bridge across the Menai Strait between the island of Anglesey and the mainland of Wales, originally a tubular bridge of wrought iron rectangular box-section spans, and now a two-tier steel box girder and arch bridge.
The opening of the Menai Bridge in 1826, a mile (1.6 km) to the east of where Britannia Bridge was later built, provided the first road link between Anglesey and the mainland.
In spite of the heavier loadings placed on it in its later life, the bridge was "one of the most easily maintained and successful railway bridges" in the UK, and "as the first really large wrought iron bridge of the girder type it has unique significance in civil engineering history".

 Menai Strait Bridges
One of the design requirements for the bridge was that it needed to have 100 feet of clear space under the main span, to allow for the passage of the tall sailing ships that plied the strait.
In the autumn of 1999 the bridge was closed for several weeks to completely replace the road surface and strengthen the bridge.
An alternative is to convert the Britannia Bridge from two to three lanes, with the traffic direction of the centre lane changing at different times of the day.

 BBC - North West Wales Llanfairpwll & Menai Bridge - History
There wasn't anything in Menai Bridge before the bridge was built and Bangor was a small town before the Britannia Bridge because it only really grew with the coming of the railway.
It is again a unique bridge in international terms because the construction itself was created out of a box girder system with rivetin - 2.2 million rivets were used and it was so strong and stable it was able to carry a full railway engine and train across.
Britannia Bridge, perhaps a mention of the memorial to those who died during its construction would be worthwhile.

The bridge was built over the Mersey at this point in order to shorten the railway route between London and Liverpool (by 9 miles).
This high level bridge was designed by the Liverpool engineer William Baker and is a three span, wrought iron structure supported on massive piers, and crosses the 1000 ft Runcorn Gap, with Runcorn lying on the south bank of the Mersey and Widnes on the north.
The bridge was built at such a height (75 feet above the river high water mark) on the insistence of shippers who demanded that the bridge be high enough to allow sailing ships to pass safely under at any state of the tide.

Completion of the Britannia Bridge in 1850 reduced the need for coaching inns (at least for mail coaches) and was appears to have been an important factor in the closing of Panton Arms at Penmynydd.
After a disastrous fire in 1970, the Britannia Bridge was redesigned and rebuilt for road and rail transport, and is now the main highway bridge across Menai Straits.
When the Britannia Bridge was completed in 1850 as a rail bridge, trains were able to carry the mail directly from the mainland to Holyhead and Panton Arms returned to its original name -- Sarnfraint (which it carries today).

 Britannia Bridge
The Menai Straits had been spectacularly bridged in 1826 by Thomas Telford, with what was then the world’s longest suspension bridge.
But by the 1840s railways were taking over from road carriages, and it was thought that a suspension bridge could not carry the load of a train.
The central tower, which supported the tubes, was built on Britannia Rock, hence the bridge was named the Britannia Bridge.

It was preceded by the Britannia Bridge, built between 1846 and 1849.
The bridge also boasted marble faced towers; originally conceived as supports for auxiliary chains which were never installed as the girders were strong enough in themselves.
Stephenson’s bridge was the first to use the hollow box girder (rectangular tubes built from wrought iron plates), a design which gave the extra stiffness of the truss and required less precision.

While the birth places of Ellin and Margaret are not known at this time, Edward's sister Harriet was living at Menai Bridge (perhaps with the family) when she died in 1846, and son John was born at Menai Bridge in 1849.
It is interesting to note that the Britannia Bridge, a 1500-foot long bridge about a mile south of Menai Bridge, was started in 1845 and completed in 1850.
The construction of that bridge over several years could have provided quite a bit of work for a wood worker - either on the bridge or in support of the families that moved in to build it.

The Britannia, a neighbor of the suspension bridge, had to be rebuilt after a devastating fire that destroyed its pitch and timberwork; it now carries both trains and cars on two different levels.

 Tubular bridge - Wikipedia, the free encyclopedia
A tubular bridge is a bridge built as a rigid box section within which the traffic is carried.
Famous examples include the original Britannia Bridge over the Menai Strait and the Conwy railway bridge over the River Conwy, both designed and built by Robert Stephenson between 1846 and 1850.
In the case of the Britannia Bridge this technology allowed a bridge 1511-ft long to be constructed, when until then the longest wrought iron span had been 31 ft 6 inches.

The bridge was later rebuilt as a two-tier structure, using the original stone piers, and now carries the railway on one level with the dual-carriageway A55 road to Holyhead immediately above it.
At the time, it was the longest suspension bridge in the world, and was built as part of the improvements to the Holyhead Road following the 1801 Act of Union, which obliged Irish MPs to travel regularly to the Houses of Parliament in London.
At the insistence of The Admiralty the Menai Bridge, like the later Britannia Bridge, had to leave sufficient headroom for sailing ships to pass underneath, thus avoiding the hazardous voyage right round Anglesey.

In the mid-nineteenth century, the Britannia Bridge was constructed to provide trains a passageway across the Menai Strait.
Unfortunately, the Britannia Bridge design concentrated so much on failure avoidance, preventing collapse under the load of a train, that cost and environmental concerns were overlooked.
The primary lesson of this chapter is that "[designers] must make a special effort to step back from each design and consider what might appear to be some of the more mundane and less challenging aspects of the problem".
