Hays County, in cooperation with the Texas Department of Transportation, is working on the RM 150 alignment project from just west of Kyle to near I-35. The purpose of the proposed project is to enhance safety, relieve congestion, and improve system linkage.

The RM 150 team has reviewed public comments and completed a screening of the Preliminary Segment Alternatives that were shared in October 2018. Two of the segments have been removed from the environmental study (P6 and D3), as they had more impacts compared to other segments. We are now moving forward to further evaluate alternatives from the north end to the south end.

Next Steps

The remaining segments will be further evaluated from end to end. Our environmental and survey teams will be conducting investigations in the field over the next few months to gather more detailed information. Once this is gathered, the 12 alternative routes will be further evaluated to identify a preferred alternative (or location). We currently anticipate completing the evaluations and sharing this information at a public meeting in late 2019 or early 2020.

We will continue to share updates as they are available. Please reach out at any time with questions or concerns.

Project History

  • 2013: Hays County Transportation Plan identified the need for RM 150 to be expanded to a four-lane divided road.
  • 2014: RM 150 Alignment Study began with a large study area to identify the preferred alignment location.
  • 2015: Four different corridors were evaluated and three public meetings were held to identify the preferred corridor. The County and TxDOT coordinated to identify roles, responsibilities, and funding for the continuation of the environmental study.
  • 2018: The environmental study continues following the National Environmental Policy Act (NEPA) as an Environmental Impact Statement (EIS).
