CRAFTING A VISION

Discussion

The Winona Bridge Project should refm ect the current era while respecting the past. The existing bridge is a visual icon for the city, and so the new bridge should defer to its prominent visual

  • presence. The new bridge should celebrate the river’s natural beauty and the cultural history
  • f Winona that is intertwined with the river. Together, the two bridges should symbolize a

welcoming gateway to beauty, culture, and prosperity.

LIGHTING

Overview MnDOT Cultural Resources General Guidance

  • Restored lighting on the existing historic bridge and new roadway/sidewalk lighting on the

new bridge will be reviewed for conformance with the Secretary of the Interior’s Standards.

  • Lighting on the new bridge should be consistent with the overall design of the new bridge,

complement the historic bridge, not replicate historic bridge features or elements, and not become a stronger design statement than the historic bridge.

  • Both the existing historic bridge and the new bridge may use or incorporate aesthetic

accent lighting, subject to conformance with the Standards.

Types of Lighting Other Considerations

  • Roadway Lighting
  • Warrant
  • Classifj

cation

  • Light Levels
  • Aesthetic Lighting
  • Navigational Lighting
  • FAA
  • Migratory Birds
  • “Dark Skies”

LIGHTING

Roadway Lighting - Existing Bridge MnDOT Cultural Resources Guidance

  • Remove existing light standards on the

approach spans installed in the 1970’s

  • If the original railings can be replicated for the

approach spans, then accurately reproduce the

  • riginal light standards for the entire bridge,

based on the information in the original plans and photographs.

  • New replica light standards (poles) on the

approach spans

  • Existing downlights in the through-truss
  • If the original railings cannot be replicated (e.g.,

due to crash testing requirements), further discussion on the light poles will need to occur.

LIGHTING

Roadway and Trail Lighting - New Bridge MnDOT Cultural Resources Guidance

  • Design new lighting that will complement

the lighting on the historic bridge, while not

  • vershadowing it

“Base” Design Scenarios

  • MnDOT Standard Light Poles
  • 40’ Tall “Cobrahead” Style
  • Currently Studying Dif

erent Layouts

“Enhanced” Design Scenarios

  • Potential Alternative Pole Style
  • Potential Additional Pedestrian Height Poles
