Yes it is for decoration. You have to remember the airport operator isn't paying for this otherwise it would have been a standard bridge made out of second hand matchsticks. The council has borrowed the £225 million for the Dart and wants something fancy. The ski slope will be back lit with LED lighting so it looks nice at night. Oh and the high bit is by the approach lights end which isn't even a full set of lights due to the road below and is less than half the length of the 26 end. If you look carefully the approach lights are on the left so the top of the bridge will make an interesting obstacle. I always thought approach lights were designed to snap off if hit by an aircraft.
