Pipeline Markers

Since pipelines are generally buried underground, we use markers and warning signs to indicate the approximate location of underground pipelines at regular intervals along the pipeline right-of-way, and at road crossings, railroads and navigable waterway crossings.

Markers do not provide information on the depth or number of pipelines in the vicinity and do not indicate the exact position of the pipeline. Pipelines may not follow a straight path between markers, which are generally yellow, black, and red in color.

Below are examples of pipeline markers:
