Minor Culvert

A minor culvert is a relatively small road culvert or number of small culverts laid side by side. The difference between a minor culvert and a major culvert is its span. In a number of Australian states culverts are considered to be minor if they span less than 6 metres.

The location of road culverts is typically indicated by the presence of two closely spaced guide posts on either side of a road.


The Queensland Grants Commission defines a minor culvert as "a culvert or culverts with a total span of less than 6m".
