Abstract

A low profile snowplowable road marker and method of installation is disclosed. The snowplowable road marker has a circular top section with opposed dished surfaces extending from a peripheral edge. The peripheral edge is mounted in an outer bore below the level of the road surface. A bridge portion extends between a pair of channels. The bridge portion has at least one inclined wall having a recess for accepting a signalling device. A brow extends outwardly from the inclined wall over the recess to reduce contact between the tire of a vehicle passing over the road marker and the signalling device.
