Grade Separations

Overpasses are the preferred option versus underpasses for grade separations. Overpasses are preferred due to:
  • Minimum disruption to rail service during construction.
  • Drainage.
  • Simplify future track expansion.
  • Simplify future highway widening.
  • Clearance issues due to
    oversized
     vehicles eliminated.
  • Pedestrian design.
  • Maintenance costs.
  • Lower
     throwaway costs.
When designing overpasses, access to adjacent properties should be considered early during project development.
