• Distinctive appearance so that bridge remains a symbol
• Stay within budget: “German Simple”
• Recognize views to bridge from downtown/riverfront
• Maintain views to downtown from the bridge
• Keep design subtle; historic feel with minimal detailing
• Light pedestrian/ bicycle trail but not entire roadway;
• Lighting should enhance structure, not draw attention to itself.
