Forestry and Agrifoods
Forest Resource Roads are constructed throughout the Province for a variety of users; the commercial harvest of timber for sawlogs and pulpwood being the primary one.
Resource roads are typically constructed by excavators and are built to specifications developed and enforced by the Forest 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 small streams. Proper installation requires placement of rock around pipe to prevent erosion of road.
Small streams are normally spanned with wooden bridges, however in the instances 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.
Metal binwall abutments have replaced the wooden abutment. The steel binwall type abutment, when installed done properly, promises extended life and relatively little maintenance.
Wire Gabion Baskets also used in place of wooden abutments, but more commonly used with wooded bridges 30 feet or less.
In terms of safety, all new bridge installations now include the erection guardrails on any structure with a height greater than 2 m. Guardrails are erected on all four corners of the bridge, extending out at a slight angle (flaring) on the shoulders of the road to approximately 4.5m
