The banners were placed on the balustrading to quite a few bridges over one weekend. A large banner was also used to hide a derelict building on Grand Parade.
The cable ties remain in place on Christy Ring Bridge – together with tens more like them. They were not removed with the advertising banner. I have not checked to see if Michael Collins Bridge, and others, are similarly decorated.
There may be zero fuel costs, emissions and parking costs. Unfortunately, Drive4zero cannot say the same regarding litter pollution.
