Project Overview and Background

Map of the project area. Centennial Park boat ramp and Riverside Cemetary are marked to the south east of the Snake river and SH-52 Bridge.

The Idaho Transportation Department (ITD) is designing a new State Highway 52 (SH-52) Bridge in Payette over the Snake River, which connects Idaho and Oregon.

Built in 1953, the bridge no longer meets current highway bridge standards for motorists, including freight haulers who transport produce across the region.

The bridge barriers, width, and surface will be improved in coordination with the Oregon Department of Transportation (ODOT).

Construction Phasing

ITD and ODOT heard from emergency responders and haulers that a full closure would greatly impact response time and access.

Bridge construction will be phased, meaning a new bridge will be constructed one half at a time.

Construction will take approximately two years.

The new bridge will include:

  • Two 12-foot lanes
  • Two 8-foot shoulders
  • New deck and guardrail
Typical sections of Phase 1, 2 and Final section of the bridge detailing where lanes will be designated as the bridge is expanded during construction.


The reconstructed roadway will include:

  • Two 12-foot lanes
  • Two 8-foot shoulders
Typical sections of roadway detailing 12-foot lane and 8-foot shoulder sections.


Project Schedule: Feasibility Study completed fall, 2021. Public Information Meeting #1 in spring 2023. Preliminary design in fall of 2023. Public Information Meeting #2 in spring of 2024. Final design in summer 2024. Construction tentatively scheduled in 2026 with possibility to advance to 2025 based on funding and scheduling availability.
