A Rotary Club spokesperson said: “The club is aware that some residents may feel that this arrangement is an inconvenience to them even if of short duration.
“We hope we can enjoy your support and patience as shown in past years, and hope when weighed against the huge benefits to charities, and the prestige this event gives the town, all will feel the event warrants the small disruption caused.”
