Design Your Own Bridge Tools

Contech’s DYOB is our exclusive online design tool to help you design your own bridge. Use this tool to create a drawing of your aluminum box culvert, plate, precast or truss structure.

All Online Design Tools are currently not available.

If you need assistance with your project please use the Look Up Tool above or the Contact Us form located here.

We apologize for any inconvenience this may cause.

Benefits include:


  • Drawings can include headwalls and wingwalls
  • Designs can include up to 12 cells (depending on bridge type)
  • Reduces the time needed to generate high quality drawings
  • Generate detailed drawings to include in proposals, design and construction meetings

Just click on the link to your specific DYOB, enter the parameters of your bridge, and receive an isometric drawing of your Contech Bridge structure via email.

Please allow an hour for your request to be processed.
