I know the A12 corridor well, I can remember it from the seventies when you had Chelmsford, Boreham, Hatfield Peveral, Witham, Kelvedon, Marks Tey and then Colchester but I went North thirty years later and by then all those places were merging as huge housing estates just joined them together and traffic conjestion was just ramping up. My commute changed from thirty five minutes to an hour and fifteen minutes, thousands more houses on the cards and for me enough was enough so got out.
In fact going further back to when living in Hornchurch as a kid we often visited Colchester zoo before the A12 was even built!
Now living up north I am now witnessing the same destruction as down south, once freindly small towns are just being swamped by housing development and their character ripped out forever, one local town that was once a desirable place to live and with property in demand has become just an urban ghetto where kids that have nothing to do just cause trouble, traffic queues throught the high street because the roads were never layed out with cars in mind and people have long commutes because there is no local work that pays a decent wage. Up here it is agriculture and farming, either livestock or holiday makers.
