Strolling down to Pompey

The opening of the Hindhead tunnel will be the most significant opening of 2011. For roadies and petrolheads it will mean the A3 is dual carriageway all the way from Tibbett’s Corner in Putney to the Dockyard gates in Portsmouth, and that the Hindhead traffic jam, the (very often literally) long-standing bane of Hampshire motorists’ life is finally unblocked. They will justifiably celebrate.

I have no idea how the ecological balance sheet stands for the new Hindhead Tunnel; most new road building seems to fall on the negative side. It will, experts say, be the longest non-estuarial tunnel in the UK so presumably the boring technology must have been pretty cutting edge. It also gives a great chance for Hindhead Common to return to a more natural state, potentially restoring, alongside the Devil’s Punchbowl, one of the most beautiful spots in the south of England.

The development also means that the first A3 London to Portsmouth road will have been, in slightly less than 100 years, almost completely shifted off its original line. The London to Portsmouth road was named as the A3 when the great road numbering system was brought in on April 1, 1923; it then ran through Kingston, Esher, Guildford, Liss, Petersfield and Cosham, and on to Portsea Island. All those towns have since been bypassed, starting with the Kingston bypass opened by then Prime Minister Stanley Baldwin in October 1927.

The old line of the A3, renumbered in various places (the Kingston to Esher road, for example, has become the A307), is now out of main road usage and provides fascinating historical snapshots of road, town and village development over the twentieth century. This road itself is a development of the various old coaching routes and turnpike roads from London to Portsmouth, and the traces of these, now that the A3 is shifted on to its new super speedway line, can hopefully be explored at greater leisure.

Which is how a retired sub-editor with a pencil, a notebook, a camera and an itch to experiment with html - http://www.londona3.co.uk/home.htm - comes to be strolling down to Pompey…
