Texas Regional Mobility Authorities

A regional mobility authority boundary (RMA) is a political subdivision formed by one or more counties to finance, acquire, design, construct, operate, maintain, expand or extend transportation projects. These projects may be tolled or non-tolled. Counties forming an RMA do not have to be adjacent to one another. The service area of an RMA may overlap with another RMA (e.g. an individual county may form its own RMA and may also be part of another RMA). Fannin County was added to Sulphur River RMA as per Minute Order number 114957 dated June 29, 2017.
