Hays County and the Texas Department of Transportation (TxDOT) continue finalizing the design of the I-35 and Posey Road Intersection improvements. The purpose of this project is to enhance safety and mobility.

The project has been environmentally cleared and right-of-way has been acquired. The County is nearing completion of utility coordination and design approvals. Construction is anticipated to begin early-to-mid 2018 and take 18 months to complete.

Changes Include

  • I-35 and Posey Road Intersection – Removing the existing Posey Road Bridge and reconstructing I-35 over Posey Road.
  • Improvements to the Posey Road intersections at the frontage roads including left and right turn lanes and turnarounds under I-35.
  • 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 will become one-way south of Posey Road for approximately two miles to York Creek Road (frontage roads north of Posey Road are currently one-way).
