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
