Serious problems did develop & the area hit rock bottom. However, after the £400m investment in South Central Manchester, in the mid-2000's the attention was turned to North Manchester & major regeneration projects were launched.
Funnily enough, the very first of which was CoMS which shows how long the plans were on the drawing board for. There's still a way to go, but it's a million times better than the drug riddled place it was in the 90s & early 2000s.
The Council are working very closely with City in North & East Manchester & it's why all the major infrastructure projects are earmarked for North/East Manchester...
