Well that's what you get when you realize you didn't build the bridges with enough space for artics, and decide to scoop out a huge divot under each one to fudge it.
Now it is effectively a series of dips with some road in-between, which mostly rests under the water table seemingly, plus they're building on the adjacent land faster than you can say "brown envelope", meaning even more water runs off the fields rather than into it.
The latest one apparently is around 3000 additional houses on fields alongside this bypass and the A34, connecting to the road network at a roundabout already described as seeing "near motorway levels" of traffic daily at a previous hearing into whether they could build a McDonald's there too, directly opposite a school. Cos that fits with the clean air and obesity targets too, once you've wash them down good and hard with a wad of cash, allegedly.
Like with the drains, they'll come along and connect their brand spanking new bits to the existing near-victorian infrastructure, and then run like hell with pockets stuffed with notes.
You'd think such an impactful event as this would give pause for thought. Double check the actual effects before you change the landscape for good. But I can guarantee we will be told this was an abnormal and unforeseeable event (if you ignore global warming and write off the less desirable environmental impact assessments) and nobody in any decision making role will even pretend to listen if asked to postpone new developments for a proper impact assessment.
Facilitate building more houses, every council is told. On green belt land if you have to. But why? Do we really need to? Kids can't afford their own home anyway nowadays, brown belt land is left to the rats and the housing market has slowed down considerably since the instruction to build was first given. Too many short sighted, short term profiteering hands in the cookie jar and Stockport is just one of many nationwide where the same scenario is playing out.
