I think even if we wanted a new stadium is there many locations it could be?
One of the best features of the lane is the city centre proximity, pretty easy to get to from interchange/train station.
No doubt council would want it on a tram route if we was it move.
The only options I can think of in my limited understand are:
a) Norton Aerodrome. There plot and surrounding area just about the right size with potential to expand into surrounding greenfield sites if needed (assuming planning law is relaxed sufficiently). Next to the dual carriageway and across from Herdings tram stop.
Residential area though and I doubt the non-football fans of Charnock, Herdings etc would be too happy.
b) Sheffield Airport. Close to the parkway and could probably shift a lot of the businesses there relatively easily if needed. A long way from other amenities though and no current public transport offer.
c) Weedon Street - there is a big patch of derelict land there and a few warehouses. Close to M1, tram, Meadowhall station and all the amenities around the retail parks and shopping centre. Think Meadowhall have been threatening to develop this bit for years though so probs a non starter.
d) switch sites with Sheffield Arena and incorporate Don Valley bowl. New state of the art arena in the city centre which would probably have space for a multi-storey car park. Blades would probably do quite well from such a deal and get a decent size spot with tram stop etc, loads of car parking etc. Amenities nearby for match days and space to build extra. Also probably some benefits to be realised being so near to the EIS.
The lack of suitable sites will, in my opinion make a ground share with the pigs inevitable, or at least will become a serious proposition in the next 20 years assuming they are still a going concern.
As much as I’d hate to move from the lane the first of the clubs to take their medicine and move to a new ground will probably have the upper hand for years to come and have a chance of sustaining themselves at the top level. Obviously though neither side has an owner with the funds so it’s not happening any time soon.
