It’s not even that. It’s safety rails so that at moments when people do go berserk, there isn’t the safety implications of people falling over seating. The sections will remain seated and people will be expected to sit down.
It also provides a very hand rail to hold onto whilst standing… not surprised it is being implemented in areas of the stadium where there seems to be a lot of persistant standing
While these examples demonstrate that it is possible in principle for a stand to “bridge” a road, none replicate the problems associated with Walton Breck Road.
Put simply, the geometry of the WBR in relation to the Kop, and the close proximity of other properties to an expanded Kop, would make the expansion a very difficult and expensive proposition.
For example, a six thousand seat expansion (assuming a continuation of the existing row depth) would create a stand that would permanently shadow The Albert, overhang the North-East elevation of Christ Church and require a bridging span of some 44 metres on the west-north-westerly approach of the road (unless permission is granted for supporting columns on the side / down the centre of the road).
By comparison the widest span on the Parc des Princes underpass is about 20 metres.
A more modest four thousand seat expansion would avoid some of these problems, but at the expense of increasing the bridging span to just over 46 metres!
I once had a childish idea that we just build a very similar/same (in main aspects), but improved/bigger version of Anfield on Stanley Park where there is more room. Basically like moving the stadium over there.
Yes, not just the stadium but the surrounds too. Used to be so depressing walking up to the ground past rows of tinned up houses. Totally different vibe now.
