As I went under the new Dart bridge today (twice) I realised why it seems incongrous to me. The'swoop' rises to meet the end of the runway but, as it appears to be designed to mimic the aircraft - it is wrong. If it were 180 degrees around, then the swoop would follow the trajectory of aircraft.
The overall height would be the same for avoidance but it would seem more correct. But then, it is only there to look 'pretty' and for
PR images.
