Culvert (on State owned roads)

A culvert is a structure, which allows water to pass under the road. Culvert is the authoritative dataset used in the administration and management of Culverts in the State Proclaimed Road Reserve by the Department of State Growth. Culverts are utilised in conjunction with the Bridges. This is one of the key datasets for the Road Information Management System (Database) and is captured and stored using a Linear Referencing System (LRS). Culverts that have a bridge number are being stored in the same database tables as bridges because they have similar characteristics. These include Dimension, Hydraulic and Maintenance. For new structures, a culvert is a structure with a waterway area less than 3.5m^2. Small culverts are stored in the Road (Minor) Culverts table, which is located under Road Inventory.
