“Now it may be their fears will be justified. This coincides with Brexit times, which is likely to hit the economy (already has - people are uncertain and spending less).”
Indeed.
Even without Brexit, the internet and all the other things outwith ‘ordinary’ people’s control, there are few certainties.
Small businesses often drift into a mindset where the attitude can be ‘I’ve made the effort to start this business so I need support from customers and the authorities’.
That street is hardly the most attractive place to want to shop. ‘We’ might argue that the traffic has a lot to do with that, others might believe it’s ‘parking restrictions’.
Both will be partly right.
It’s easy to believe that the cycle route, extra pedestrian crossing will help the traders. It’s also easy to believe that any upheaval will result in shops closing (see tramworks/Leith Walk).
But the simple truth is that in recent years many businesses - big and small - in many streets have closed. They didn’t all have cyclelanes built outside.
