Since 2014, Hays County has been studying the portion of RM 150 from just west of Arroyo Ranch Road southeast to I-35 near Yarrington Road. As Hays County and the Kyle area have continued to grow at a rapid pace, the need is greater than ever for additional roadway capacity to address increasing traffic volumes and improve safety on this section of RM 150.

A proposed alignment that would help alleviate congestion along existing RM 150 and through downtown Kyle has been identified through an evaluation of several options, technical analysis, public involvement, and coordination with property owners. Hays County previously worked jointly with TxDOT on this study but is now leading the effort as a County project to move design forward and preserve the necessary right of way for the roadway, considering several developments in the area that are moving forward quickly.



Public comments continue to be collected and reviewed while the roadway design schematic and preliminary drainage are being developed. The right of way preservation process will be coordinated with individual property owners. Final preliminary design with environmental due diligence is anticipated to be complete in 2021.

There is not a timeline for construction as funding has not yet been identified. As the design is refined, right of way preservation will begin and construction details will be coordinated. Final design and construction may occur along the corridor in phases, depending on funding availability and conditions in the area.
