Geotechnical and erosion control

Overview

The design and construction of roads, and bridges, is a matter of judiciously applying the concepts of soil and rock mechanics.

Existing and newly constructed infrastructure is subject to ongoing geohazards. These geohazards might be a rapid landslide or rock fall, or might be a slower process such as wind or water erosion.

This page provides links to design manuals, the department's annual geohazard risk management assessment reports and other useful information related to geotechnical and erosion control.
