Seven crossings of the River Severn

This is the story of a day spent exploring seven crossings of the River Severn below Gloucester as it morphs from a meandering river into a mighty tidal estuary flowing through the Bristol Channel and on into the impossible immensity of the Atlantic Ocean: three ferry passages, a railway bridge, a railway tunnel and two road bridges. Of a backwater estuarine landscape dissected over the centuries by communication routes ferrying goods and people from the coalfields and iron foundries of South Wales, the Irish Sea port of Fishguard and the timber lands of the Forest of Dean to Bristol, London and beyond. The road bridges and railway tunnel remain, transporting their sleek machines between England and Wales, but the railway bridge is lost beneath the water and the ferries are long gone, given a last hurrah, curiously, by Bob Dylan in 1966.

  

First up an attempt to view the eastern entrance to the Severn Railway Tunnel. Constructed between 1873 and 1886, this subterranean 'crossing' is over 4 miles and long and, until the opening of the Channel Tunnel, was the longest in Britain's railway system. On the map this looks an easy stroll from the road, but this is a working mainline and I predicted that access could be tricky; and so it proved to be. Although a public footpath circumnavigated the entrance, its location in a deep cutting bounded by overgrown embankments and ditches prevented any possibility of viewing from the right of way. High steel fencing completed the sense of prosaic impregnability. If Railtrack were responsible for designing the ramparts and palisades of Iron Age hill-forts, this is how they would look. 

So, a detour is required across fields, marked by the humps and bumps of medieval ridge and furrow, to clear the range of the security fencing, negotiate a more conventional wire fence and plunge into bush and brier to ascend the embankment. Eventually a way is found through the nettles and thorns and a view of the cutting is won. Sadly, a service road in full sight of a nearby maintenance depot would need to be crossed to obtain a full view of the turreted tunnel entrance. A little disappointed, I retrace my tracks and notice that the gate to the depot is now open. Two fluorescent coated workmen are preoccupied with checking machinery and do not notice my brief trespass to the top of steps down to the tunnel entrance; and so I get the close-up photo I had been seeking.

As I trudge back to the car I muse on whether it should need to feel this subversive - should require a mild law-breaking adventure - in order to see a wonder of Victorian engineering. I'm sure a National Trust style visitor centre would diminish the experience in a different way, but there must be a happy medium. 

Half a mile away at New Passage and the ghosts of an older method of transportation, the ferry, haunt the shadows of the Second Severn Crossing Bridge, the gleaming conveyor of the M4 motorway across the estuary. Until the railway tunnel opened (almost directly beneath) the New Passage Ferry was the most direct connecting route from South Wales to England if a long circuitous route north via the bridge up-river at Gloucester was to be avoided. An example of the impossibly localised companies that sprang up during the railway mania of the mid-nineteenth century, the Bristol & South Wales Union Railway opened a line to a terminal pier here for passengers to board the ferry across to Portskewett. The ferry route's lifetime was though short-lived and it only operated between 1863 and 1886. The pier is long gone but its stone bulwark forms part of the flood defence topped by a foot and cycle path which gives suitably breath-taking views of both the Second Severn Crossing bridge and the original Severn Bridge just three miles further upstream. Opened in 1996 to provide a more direct route for the increased traffic volumes of the M4, the new bridge seems to display a haughtiness towards its precursor as it curves away southwards. Seen from the heights of the Forest of Dean or the Cotswold scarp the two structures seem like diverging monolithic siblings, two contrasting characters forever linked by their utility.

A short walk before a pub lunch this morning in the expectation of more Spring sunshine. Instead a layer of early morning mist was still stubbornly hugging the low-lying fields bordering the Severn Estuary as midday approached; the eeriness emphasised by the regular low honk of an unseen ship's horn on the estuary seeping through the fog. The strangeness reminds me of the nearby Whale Wharf, so-named after a whale was stranded on the shore in the late nineteenth century, became a brief tourist attraction and was then towed to Bristol to be turned into fertiliser.
