ForterraArch

ForterraArch is a fully engineered, site specific structure. The arch-box shape provides an attractive, economical, rugged structure with exceptional load carrying capacity. ForterraArch bridges and culverts can be designed with natural or paved channel inverts, making them ideal for all situations. ForterraArch offers many benefits, including:

  • End treatment options, including plain, finished with precast or cast-in-place head and wing walls
  • Straightforward, simple installation process
  • Segments are precast, allowing easy shipment for rapid installation
  • Beveled sections facilitate curved alignments easily
  • The covered structure is maintenance free once installed and backfilled

Applications

  • Culverts
  • Storm Drains
  • Undercrossings
  • Vaults
  • Retention structures

Sizes

ForterraArch sections are furnished in spans of 12 ft through 60 ft. Rises are available up to 12 ft, but may be increased by placing the precast sections atop cast-in-place stem walls.
