Hays County Post Road Alternatives Analysis

Hays County, TX
Preliminary Study & Roadway Alignment
Quick Facts
  • Existing alignment passed under a span of the adjacent railroad bridge
  • Post Road bridge was originally built as a low-water crossing
  • Project addressed multiple deficiencies that affected the bridge’s ability to safely convey traffic

KFA prepared preliminary roadway horizontal and vertical alignments, developed preliminary bridge layouts to span the floodplain, and performed a preliminary hydraulic impact analysis of the proposed improvements.  In addition to the existing railroad bridge, Union Pacific Railroad also required consideration of future additional tracks and a new bridge.  A major design consideration was for a new bridge and roadway alignment to meet the county’s requirements for overtopping without producing unacceptable upstream flooding impacts.
