Britannia bridge

Visited with Jack
After seeing this one recently on the internet and it being minutes from my house, I decided to visit this one. Once I got on there and started snapping away, I realised that it was going to be difficult to get some pictures that were different to what have previously taken and posted on here by others. Decided to await darkness, and see what I could get in way of long exposure and light painting shots.

History
Britannia Bridge (Welsh: Pont Britannia) is a bridge across the Menai Strait between the island of Anglesey and the mainland of Wales. It was originally designed and built by Robert Stephenson as a tubular bridge of wrought iron rectangular box-section spans for carrying rail traffic. Following a fire in 1970 it was rebuilt as a two-tier steel truss arch bridge, carrying both road and rail traffic.
Construction started in 1846, the bridge was opened on 5 March 1850. For its time, it was a bridge of "magnitude and singular novelty", far surpassing in length contemporary cast beam or plate girder iron bridges.
During the evening of 23 May 1970 the bridge was greatly damaged when boys playing inside the bridge dropped a burning torch, setting alight the tar-coated wooden roof of the tubes. Despite the best efforts of the Caernarfonshire and Anglesey fire brigades, the bridge's height, construction and the lack of an adequate water supply meant they were unable to control the fire which spread all the way across from the mainland to the Anglesey side. After the fire had burned itself out the bridge was still standing but the structural integrity of the iron tubes had been fatally compromised by the intense heat. As a consequence the bridge was completely rebuilt. The new design had spans which were supported by additional archways. The new bridge reopened to rail traffic (albeit with only a single line of rails rather than the twin tracks that existed prior to the fire on 30 January 1972.In 1980, almost 10 years after the fire, the upper road level opened which carried a single-carriageway section of the A55 Road. 

Healey Mills Marshalling yard

The Healey Mills Yard occupies a now derelict 140-acre site, the whole of which is underlain by a series of coal seams. Although the yard contains 120 sidings comprising 57 miles of track, at the west end there are 14 reception sidings leading to the hump; there are 50 main sorting sidings and 25 secondary sorting sidings; 15 staging sidings and 13 departure sidings.

In an open yard working round the clock, a high standard of artificial lighting was used during the hours of darkness was essential. This was taken care of by eight 150ft. high steel lighting towers, The floodlights at the top of the towers contain 1500 watt lamps arranged in banks. On five of the towers, lighting is on all four faces, and on the other three towers, on three faces only. All of these towers remain, but at the moment, only one of these towers is turned on at night. The other towers do seem to be powered too, otherwise I would have been straight up them.
