Can you build a boardwalk over wetlands?
While many wetland boardwalks are permitted and built with marsh buggies or cranes placed on large mats in the wetlands, invasive machinery like this can be avoided by designing the boardwalk to be installed from above. This method is called top down construction.
How are boardwalks built?
A. Most boardwalks are constructed of pressure treated four by four’s or six by sixes (pilings) with two by six or two by eight cross members and two by six or two by eight deck material. However, some boardwalks also use two by tens for decking and cross members for longer spans or heavy use.
Can you build a bridge over wetlands?
In fact, for building on wetlands, helical piers are the most effective solution to support paths, bridges and walkways.
How wide should a boardwalk be?
The average sidewalk or boardwalk is 42” wide. Your supports can handle stringers on three-foot centers, with a six-inch cantilever on each end of the slats.
How thick is a boardwalk?
The minimum width for our boardwalk is 3′-9″, and it increases all the way to 15′-4″ wide. PermaTrak has standard concrete boardwalk tread widths of 3′-9″, 7′-6″, 11′-3″ and 15′-4″. For the most economical material cost, these tread sizes will be used.

For all boardwalks, it’s important to consider cost, aesthetic appearance, durability, and maintenance requirements of various materials.
What are the environmental challenges of building a boardwalk?
To dig right in, this project pitted a variety of environmental challenges against the special requirements of the boardwalk. First and foremost, protection of the wetland plants and animals inhabiting the river and surrounding marshes topped the priority list.
What Wood is used for wetland boardwalks?
