7. Bridge Requirements Interchange structures need to announce entrance to airport = landmark Bridge needs to be compatible with new terminal building = element of overall composition Bridges are a platform to view Indiana landscape / new terminal entrance axis = de-emphasize barriers Arc of alignment is dynamic = suggestion of movement, flight High skew from alignment results in long spans. Emphasize span and bridge lengths = horizontal nature of landscape
