These restrictions seem to be less about football and more about the Arena and a concern that concerts 52 weeks a year will create permanent car parking issues in the area. But the big impact is clearly for City home games. The difference between an Arena capacity of 23,000 against Stadium capacity of 55,000 rising to 61,000.
I don't know what the car parking capacity is at the moment, but I would presume that a mix of Campus car parking, private car parking and public transport will be sufficient to manage the Arena. Although the proposed break in the line from Piccadilly just as the Arena is opening, shows a severe lack of forward planning. It needs (but I doubt it will be provided) and full capacity replacement bus service out of the city centre even if they manage to create a New islington to Ashton only tram service.
So that leaves a disproportionate impact on City home matches. At the moment I park in the City Centre in one of the few free spots not affected by these proposals. But from what I can see of the HS2 proposals I presume it will get swallowed up in those. I have on one occasion when the traffic was awful parked at East Didsbury, which has the advantage of EV charging so whilst I'm fit enough to walk in and out of the city centre, that might be an option. But I really don't fancy the scrum at the Etihad Tram stop if ever I cant manage the walk back to town.
I do quite understand the desire to encourage us not to use cars - but it has to be linked to a good quality reliable affordable public transport system - and Manchester is no where near having one of those.
