If you're within daily exercise distance of George Street, it's worth a wander up there under the lockdown in order to fully visualise what George Street could be like without motor vehicles.
Last night there were maybe 10 cars parked on it (which suggests that the parking demands from residents are somewhat overstated). I walked the full length down the cobbled parking bit and soaked it up.
I remember at the information day at the City Art Centre one of the design team telling me that George Street was too wide to fully pedestrianise. The scale wasn't appropriate and it would feel too empty. Based on last night's experience, I can heartily disagree with that sentiment. It would make a fantastic space for people, with lots of room for on-street activity whilst still allowing for free movement of folk on foot, bike and delivery trolley.
