Bridgescape, LLC

Bridge Typical Section

• 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.
