Challenges with Current National Standards

  • Standard is to close the sidewalk and detour peds
  • Results in improper pedestrian movements
  • Restricts safe access to businesses
  • Adds sign clutter which reduces focus on regulatory signs
  • Work zone signing can be confusing
  • Work zone signing prone to incorrect installation
  • Detour and work zone signing is mostly ignored
  • Not truly in compliance with ADA
  • Access not provided to locations along the closed sidewalk
  • Sidewalk network is not always available

    • Children on bikes moved into lane to pass work zone
    • Vehicle avoided striking children by hard braking
    • Not in compliance with federal and state law
    • No feasible alternative prior to SpanPath
