LIGHTING

Roadway and Trail Lighting MnDOT Cultural Resources Guidance

  • Existing Bridge - accurately reproduce the original light standards
  • New Bridge - design new lighting that will complement the

lighting on the historic bridge, while not overshadowing it

New Bridge “Base” Design

  • MnDOT Standard Light Poles
  • 35’ Tall “Cobrahead” Style, LED
  • Recommended location - interior barrier between the trail and

roadway

  • Spacing - approximately 130-150 ft

New Bridge “Enhanced” Design Options
