The TxDOT Mile Markers service layer is a statewide dataset of points representing one-mile intervals along on-system routes.
The Markers represent roughly one-mile intervals on IH and US center lines.  They aren't representative of the true M-value (mile measure along a route).  That number can be found in the 'M_Value' field.  This service was published by Jessica Lane in the Data Management section of Transportation Planning and Programming Division per a request.  It was created based on the version of TxDOT_Roadways on AGO as of 6/10/2019 and with the use of some ESRI geoprocessing tools including 'Generate Points along Lines,' 'Make Route Event Layer,' and 'Locate Features along Routes'.  It is subject to change.<div><br /></div><div>Update Frequency: TBD</div><div><br /></div><div>Source: 'TxDOT_Roadways' service on AGO as of 6/10/2019.</div><div><br /></div><div>Security Level: TxDOT Organization</div><div><br /></div>
