That bridleway was fully resurfaced back in August 2003. At the time I said that it had been badly done and wouldn't last very long, but Stockport Council insisted that it was all done to the relevant standards and highest quality. It lasted about 18 months at most before it began to break up, and within 3 years you couldn't tell any work had been done, expect for the large piles of gravel accumulating at the bottom.
Hmm. As it's a bridleway it has, by definition, to be suitable for horses and this definitely sounds as if it isn't. In fact to this horsewoman of nearly 58 summers (and winters) riding experience it sounds downright dangerous.
Mind you, Stockport have never been noted for being horse-friendly. For some time, despite regular complaints from Stockport East Area Bridleways Association, they had been resurfacing roads with an extremely slippery compound which was lethal for metal shod hooves even at a walk. (And horses
do have a right of way on the highway, in fact some main roads and side roads in the borough are also bridleways, so don't start with the horses shouldn't be on the road argument, thank you.)
