Wooden posts or stakes or stone slabs are driven or dug into the ground and markings are made on them. The markings might be in the form of discs painted onto flat sides, routed or sandblasted circles, arrows or symbols infilled with paint, or rings routed/sandblasted around the posts and filled in with paint. Several […]

Painting trees
In forested countries tree-trunks are often painted with markings. Sometimes circles of paint are used; a circular template is placed against the tree, and the marking is applied by spray can or brush. In other places like Sweden smooth rings are shaved in the rough bark of pine trees and a complete ring painted around […]
Forms of waymarking
There are a number of methods of marking routes. Care is needed to ensure consistency in the form of waymarking used along the routes. This is particularly relevant if posts are used, as their design may need to relate visually to other artefacts such as information or interpretation signs. All methods must strike a balance […]
Waymarking
Many visitors to the outdoors are not experienced in the use of map and compass. They are apprehensive about following a trail unless they know where it will lead them, and that they will not get lost. Hence some kind of waymarking is frequently necessary to help visitors enjoy the experience of exploring the outdoors. […]
Bridge siting
Bridge decks must be set sufficiently above the water level to allow for high flood levels, and to prevent them from damming the stream with debris and causing damage nearby or the collapse of the structure. Where the stream or river is in a region with extremes of climate, flash floods can cause water levels […]
Suspension bridges
These have been used as footbridges for centuries— for example, the rope structures used by the Incas of South America. There are several varieties of suspension bridge, depending on the setting and the amount of use expected. The simplest and most challenging type consists of four cables slung across the stream. Boards are lashed across […]
. Cantilevered beams
In this construction the beam is not a single unit laid on an abutment at each end. Two beams are used, each fixed at one end with the other projecting over the stream that is to be spanned. The two beams meet each other and are bolted together, or for longer spans the central gap […]
Sawn timber
This is more appropriate in less wild settings. Two or three beams can be sawn out of solid wood, being proportionately deeper than wide, laid parallel to each other with a decking of sawn boards fixed across them. Some bracing to prevent differential movement between the beams might be needed, with handrails bolted to the […]
Simple beam bridges
These can vary from simple structures, such as a log laid across a stream, to composite steel and timber construction. The form to use will depend on the weight to be carried and the setting in which the bridge is to be erected. In wild settings, particularly those with forests, adequate and functional footbridges can […]
. Bridges
The main problem with fords and stepping-stones is how to cross the stream during high water. Although advice on alternative routes can be provided, if flooding occurs frequently and the trail is popular it is better to have bridges. Where people with disabilities are encouraged to use the trail, bridges are a necessity. Apart from […]
