Bridges


Spooner Machine trail bridgeOur bridges are engineered using outside P.E. who considers site-specific issues while including feature requirements (length, width, weight requirements) within the design.

All steel structural members are Core Ten tubing featuring rust once surfaces so no paint necessary ever.

Our piling choices vary from site to site depending upon soil conditions, reach needed, cost and environmental concerns. Pilings available are H Type, Helical and Wooden. Typical applications or cost / benefit for each type are, H piling typically are more expensive but can be driven at a greater distance. Load is created by the friction generate from driving the pile into the ground. Spooner Machine bridges are great for snow mobile trails H pile requires more soil control because of the size and support equipment necessary during installation. Helical pile typically is less expensive and less intrusive to soils than H pile. Twisting pile into the ground creating resistance generates helical pile loads. Disadvantage is reach to pile location. Wooden pile is the most cost effective but may require excavation and soil stabilization. Load is generated from surface contact of wood and soils.

Some things you should consider prior to your bridge project:

  • Do I need abutments?
  • Should a core sample be taken?
  • Will a budget number be necessary?
  • What proper environmental action needs to be taken?
  • What season is best to build?
  • Bridge site and approaches consideration
  • What is the minimum clearance over span?
Soil Control

These are a few areas that may
affect the cost for your project.

We help you take these things into consideration to help you meet all requirements for Walking, ATV, or snowmobile bridges.
