170th Street Thorn Creek Improvement Project

Project Overview

The 170th Street Bridge Over Thorn Creek Improvement Project is a bridge replacement project. The Preliminary Engineering phase of the project is currently underway. During Preliminary Engineering, the project team will develop several design alternatives and conduct environmental and engineering studies to determine the preferred alternative. The preferred alternative will be presented at a public information meeting to receive input from the community. Community members can also provide feedback prior to the public meeting through the project comment form. The finalized preferred alternative will be carried forward into final design, and construction of the new bridge is targeted for 2025.
