This bridge would be elegant and practical… if it was ADA compliant.
Maybe if we bend it. But then there must be a landing.
Maybe extend it a foot. You forgot about the landing before the doors.
How short is too short? About 30 feet short of compliant.
Above all else, code has most affected the design. Beauty and feasibility are vital, but law is essential. What was once a smooth line from door to sidewalk has acquired curves, steps, hand rails, and above all, size. This is not complaining about a ruined concept, though. Another lesson is taught: with constraints comes more creative thinking. The project would be infantile if not forced to grow.
