• 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• Potential Alternative Pole Styles
