Hi, thank you for your message.
We are sorry to hear about the litter and will endeavour to clear this as soon as possible. We do monitor and clear the litter each working day; however there will be times when it is more evident than others, particularly first thing on a Monday. Unfortunately this process was delayed this morning due to our labour personnel ensuring our working areas and scaffolds were appropriately gritted for safety reasons following exceptional low temperatures and freezing fog in the early hours.
As you correctly point out, unfortunately the yellow flashing lights are not working. We are investigating this and will carry out repair work as soon as possible.
