The 170th Street Bridge Over Thorn Creek Improvement Project is a bridge replacement project currently in the preliminary engineering phase. During this phase, the project team developed several design alternatives and conducted environmental and engineering studies to determine the preferred alternative. The preferred alternative was presented at a public information meeting on July 12, 2023 and input from the community was received. Community members can also provide feedback at any time through the project comment form. After the final design of the preferred alternative, construction of the new bridge is targeted for 2025.
