Pipeline Locations

Gas transmission pipelines are usually located underground, beneath creeks, rivers, highways, roads, farmland, and parks, and near homes, businesses, schools or other community centers. They are in rights-of-way (ROW) which are property easements acquired by the pipeline company that run contiguously in order to deliver fuel to markets.  ROWs can be permanent or temporary acquisitions.
