Southern Oregon Seismic Triage & Resiliency Project

Design Phase

Region 3: Southwestern Oregon, Region 4: Central Oregon (Ashland, Central Point, Eagle Point, Grants Pass, Medford, Talent, Douglas, Jackson, Josephine, Klamath)

This project reinforces key slopes and bridges in southern Oregon so the region can remain connected and recover after a major earthquake.​​


Construction Impacts

​During bridge repair and reconstruction, there will be some delays and out of direction.

Meetings and Events

​​Several open houses are planned, both in person and on line depending on project schedules and ongoing COVID-19 concerns.


It's anticipated the first bridges will be under construction by 2021 with slopes being reinforced beginning in 2022. Instead of one large project, this project is split between slopes and bridges for cost efficiencies.



This project reinforces unstable slopes and vulnerable bridges in southern Oregon. By doing so the region can begin recovery efforts and maintain lifeline routes after a Cascadia Subduction Zone earthquake.


I-5 |
  • Interstate 5 from Medford/Ashland to Eug​ene.
  • Oregon 140 between Medford and Klamath Falls.​

Cost and Funding

$35 million is earmarked for this project by the 2017 Keep Oregon Moving act passed by Oregon Legislature.


Southwest Oregon residents and their economy will benefit from this project by recovering as quickly as possible after a subduction zone earthquake.

It is anticipated that the lifeline routes will be strengthened so freight and recovery materials can be transported in and out.

Triage is in the title of this project because it takes the easiest, least expensive slopes and bridge to repair to maintain connections after a massive earthquake.

Additional Information

This resilience project is based on repairing bridges and slopes on two major routes into and out of southern Oregon. 

Bridge repairs are currently underway (spring/summer 2020) on the I-5 Bridges over Leland Road, near Sunny Valley. 
Bridge repairs are planned soon on the I-5 bridge over Foothill Road near Grants Pass.

Rogue Valley Highway Bridges:

In 2022, the three bridges on this highway between Rogue River and Gold Hill will be replaced consecutively. They are:
  • Miller's Gulch Bridge: this bridge will take about a month to replace between the months of June and September. 
  • Foots and Birdseye Creek Bridges: These other nearby bridges will take more than two weeks each to complete.
  • Residents on this section of Rogue Valley highway should plan for extra travel times to either I-5 Rogue RIver (Exit 48) or Twin Bridges (Exit 45a).
​See identified bridges and slopes in the information below.
