Forest resource roads are constructed throughout the Province for a variety of purposes; with commercial harvesting of timber being the primary one.

Resource roads are typically constructed by excavators and are built to specifications developed and enforced by Fisheries and Land Resources.

Siltation of streams and lakes is of utmost concern to the Department. Strict adherence to construction guidelines is mandatory.

Steel culverts are used to control surface runoff and direct small streams. Proper installation requires placement of rock around the pipe to prevent erosion.

Small streams are normally spanned with wooden bridges.  In the instance of large streams and rivers, steel panel bridges are utilized.

Filter fabric, seeding, straw bales and straw mats are used in situations where siltation may be of concern.

While resource roads are available for public use; they are sometimes closed during periods of freeze and thaw to prevent excessive damage.

For the most part, metal binwall abutments have replaced wooden abutments. When installed properly, metal structures result in low maintenance and extended life of the construction.

Wire Gabion Baskets are also used in place of wooden abutments but are more commonly used with wooded bridges 30 feet or less.

In terms of safety, bridge installations include the erection of guardrails on any structure with a height greater than two metres. Guardrails are erected on all corners of the bridge and extend out at a slight angle (flaring) on the shoulders of the road to approximately 4.5 metres.
