I had another butchers at the carbuncle that has been bolted over one of the entrances now that all the panels are up. Seems to be made from stretched canvas in various shades of off white that looks a tad dirty in places already. Aesthetically it would have been better if the colour matched the rest of the building. I have come to the conclusion that LLAOL, who is funding the expansion to 18 million rather than LLAL who is funding MS2 and the DART has run out of money as the project is already 60% over budget. They were probably obliged to fit a canopy so this is their effort to meet their obligation. In reality it will be just used as a smokers shelter so passengers will be fighting their way through a haze as it serves no other purpose.
As for the mystery wall? With a curve now going in by the terminal it would seem that if a passenger walks from the drop off area and keeps right they will go up a slope. If they keep to the left by the bus station they will use stairs. The second entrance with the carbuncle will be initially served by a temporary slope from the bus station until the rest of the wall is complete.
