  • Sho-fly detour
  • Offset alignment
  • Traffic thru construction (staged construction)
  • Special traffic "events" to avoid
  • Conflicts with other State and/or local projects
  • Accident Data

Geometrics

  • Review Bridge SI&A data for functional obsolescence
  • Consider width requirements for AADT, % Trucks, accident data, route continuity
