The ski slope and supports wasn’t painted before it was transported down the hill so the road has got to be closed for painting. Think the airport approach road and the A1081 are meant to be closed overnight this week but the work might have been delayed.
As for the bridges appearance, it looked impressive when being built by the Ibis and not so impressive when it was first erected as it is on a bend in the road so only a quick glimpse is seen. Now the ski slope looks rather pointless after driving under it many times. I am sure it has cost a small fortune to build and added to the cost of transporting the bridge as the front support actually needed its own temporary supports to hold it in place.
Also looking at the video the top of the slope appears to be much taller than the approach light.
