Bridge design specifications:

  • Follow AASHTO and/or NACTO guidance (minimum 8' width)
  • Plan for both pedestrians and bicyclists
  • Safety - Bypass dangerous and/or impractical at-grade crossings
  • Directness - Leverage demand for the shortest path, usefulness
  • Network necessity - Reinforce need with connectivity on each side
  • Impact - Flip cost into benefit: safety, economic, equity, environment
  • Prominence - Create iconic structures as a legacy for future generations

Bridges

SLIDE 26

East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

Bridges vs. Crossings

  • At-grade design solutions:
  • Should be prioritized instead of a bridge (where possible)
  • Benefits users by reducing speeds and encouraging multi-modal, sustainable transportation
  • Help trail users avoid climbing and descending a bridge
  • Particularly helpful for those with physical disabilities and issues with mobility
  • Formalize bike/ped crossings that would still likely occur (despite being illegal and less safe)
  • Cost is much less than engineered bridges
