KY 330 over Short Creek

  • Project Owner: Kentucky Transportation Cabinet
  • Location: Pendleton County, KY

     The Kentucky Transportation Cabinet selected J.M. Crawford & Associates to provide grade, drain, surfacing, right-of-way, utility relocation and structure plans for this bridge replacement project.

     Several deficiencies were addressed through this project. The existing bridge was structurally deficient and functionally obsolete. In addition, vertical curves at the ends of the bridge did not meet geometric criteria for even a 25-mph design speed.

     This project provided a new bridge just upstream of the existing location and along a slightly improved alignment. The geometric features of the new alignment meet criteria for a 55-mph design speed. Traffic was maintained on the existing bridge during construction. With three spans (45´ x 90´ x 45´) consisting of Type 4 PCIBs with an 8-inch concrete slab, the new bridge is a little over 183 feet long. Built straight at a 20° skew, the deck was designed to accommodate a curved alignment. The new bridge deck is several feet higher than the existing – a byproduct of improvements to the vertical geometry.

     J.M. Crawford & Associates studied alternative alignments and developed roadway, right-of-way, utility relocation and structure plans for this project. The project was let to construction in the summer of 2016 at a cost of $1.78M.
