Fair point Panic but are staff not on site at early hours anyway to receive deliveries from wagons that arrive and park up overnight anyway?
Also, and as a slight change to my original suggestion, lorries not permitted during rush hour times.
This is not a final solution but just the hopeful ramblings of someone who had to find a way past a delivery wagon in the middle of Otley on wednesday.
Am sure with a little bit of co-operation between all parties, a solution could be reached.
