I think that The Arches on Gloucester Road should be a focal point entranceway into the city centre. At the moment though, the area is a bit of an eyesore. The bridge itself needs a good clean up and the graffiti removed - maybe even a repaint.
The other major problem is litter and rubbish, especially around the fast food outlets. I have been asking council officers to look to see what can be done to improve the situation. There was a bit of a clean-up about two months ago and things improved for a while before getting bad again.
Part of the problem is that a lot of the businesses dispose of their waste from the street. They obviously have to handle it somehow, but it often gets kicked around and once an area starts to look dirty and full of litter then people are less careful about how they throw things away. It's a vicious circle.
I've just heard back today that a number of businesses have now been fined for failing to dispose of their waste properly and legally. This is really good news and should help quite a bit. Also, more effort is being put into helping the residents of the flats above the shops to have sensible systems of putting their rubbish out.
The wider issue, of course, is how you reduce waste of all sorts. I'm very proud that residential recycling improved massively under the 2005 to 2007 Lib Dem administration (from 12% to 40%), but most businesses could do much, much more...
