Forestry bridges with heavy loading

Customised Forestry Bridges 

Time sensitive harvest operations and challenging access often require a bridge to cost effectively complete the project. As specialists in small to medium bridge construction, we build bridges between six to fifty metres with heavy loading capacity for forestry sector clients. 

Your infrastructure needs and site constraints require a customised solution. Our team will work with you to define the best crossing solution, whether it is a permanent, relocatable, low level submersible or temporary bridge. We offer a range of bridge types that meet HNHO-72 bridge loading standards: 

Steel beam timber deck

  • Ideal for carrying tracked machinery
  • Can be designed for disassembly and relocation

Steel beam concrete deck

  • Ideal for longer spans
  • Cost effective - longer span can reduce requirement for retaining and the lifespan of concrete deck

All concrete

  • Best for short spans of 6 -12 metres or sites which have good crane access for longer spans
  • Can be designed for low level submersible requirements (link to the low level page once built)

Temporary bridge hire

  • Short span temporary bridges available for rental Ideal for smaller harvest lots where you don’t want to outlay money on capital assets
Our experienced team will present different crossing options and recommend the optimal bridge based on your: 
  • Infrastructure needs
  • Desired lifespan
  • Maintenance requirements
  • Budget 

We operate a no-surprises pricing policy to give you certainty and peace of mind. Contact us today to discuss your infrastructure needs for your upcoming harvest.
