Thank you for your interest in improving Hays County transportation safety and mobility. Contact information is provided below should you have comments or questions.
Hays County and the Texas Department of Transportation (TxDOT) are considering modifications to the I-35 and Posey Road Intersection. The purpose of this proposed project is to enhance safety and mobility.

Changes May Include

  • I-35 and Posey Road Intersection – Removing the existing Posey Road Bridge and reconstructing I-35 over Posey Road.
  • Six ramp reversals – Changing entrance ramps to exit ramps and exit ramps to entrance ramps. Locations include Centerpoint Road, Posey Road, and FM 1102 (York Creek Road).
  • Modifications to the elevation of one ramp at Posey Road.
  • Conversion of two-way frontage roads – At the start of construction, frontage roads would become one-way south of Posey Road for approximately two miles to York Creek Road (roads north of Posey Road are currently one-way).
  • A median-divided I-35.

Project Schedule

  • Mid-2013 – Project started
  • April 2014 – Public open house
  • Mid-2014 – Project revised to include additional work
  • January 2015 – Public open house
  • 2015 – Development of updated project schematic and environmental documentation
