Southern Oregon Seismic Triage & Resiliency Project

Construction Phase

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

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


Traffic Impact

​Depending on the bridge or slope being worked on there will either be no delays, short delays or full closures with some out of direction travel. 

Construction Impacts

​Depending on the bridges and phases of construction, there may be a variety of impacts, such as single lane closures or full closures with some out of direction travel.

Meetings and Events

Visit the online open house to see more about the project:​.​


Bundle #1: 
Improvements are complete on the I-5 Exit 80 Glendale bridges.
Since October, crews have been improving the I-5 Exit 58 bridges in Grants Pass. Completion estimated spring of 2022.
Crews are scheduled to begin the I-5 Hillcrest bridge November 2022 through May 2023. Local traffic will see a full closure of Hillcrest Road. Neighbors to the east of I-5 will need to use Beacon Drive.

The first set of bridges are complete on the I-5 Leland Road bridges at Sunny Valley​.

Bundle #2:
Includes four bridges on OR 140 east of White City and the Sutherlin Creek Bridge on Del Rio Road, northwest of Roseburg. 
Crews are currently working on Lick Creek and Little Butte Creek Bridges. Expect short delays due to temporary signal at these locations.

B​undle #3: 
This bundle is slated for construction in in late 2023 will replace three bridges on OR 99 (Rogue River Highway) between City of Rogue River and the I-5 Exit 45A interchange.  They are Foots Creek, Birdseye Creek and Millers Gulch Bridges.

It's anticipated the first slopes will begin in 2023.

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 north to Eug​ene.
  • Oregon 140 between Medford and Klamath Falls.​
  • Sutherlin Creek Bridge on Del Rio Road in Douglas County.

Cost and Funding

$~45 million is earmarked for this project by the 2017 Keep Oregon Moving act passed by Oregon Legislature.


​H.P. Civil of Stayton is the contractor for the first bundle of bridges.

Carter and Company of Salem is the contrator for the second bundle of bridges.


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

Lifeline routes are being strengthened so freight and recovery materials can be transported in and out of southwest Oregon. It's anticipated there may be future bridge reinforcement projects.

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

What Problem Will This Improve?

Bundle #1
​Contractor HP Civil is currently working on the I-5 Exit 58 bridges.
The nearby I-5 Hillcrest Drive bridge is scheduled for work Nov. 2022- May 2023. There will be a full closure of Hillcrest Drive under the I-5 structure. Local traffic detour via Beacon Drive I-5 undercrossing.

Bundle #2:

Beginning January 17 through September 1, contractor Carter and Company of Salem is scheduled to begin work that affects traffic on the following bridges:

  • Little Butte Creek Bridge at MP 7.75 (March 22 - Aug. 30)
  • Schoolhouse Creek Bridge at MP 8.46 (Jan. 17 - March 21)
  • Lick Creek Bridge at MP 9.15 (March 23 - May 25), and
  • North Fork Little Butte Creek Bridge at MP 15.44 (March 23 - May 25).

The Sutherlin Creek Bridge on Del Rio Road, northwest of Roseburg, is the last bridge in this bundle. Work is set to start on that bridge June 8 - September 1 with a one week full closure, the week of August 8-13.​

Bundle #3:

​Rogue River Highway Bridges:
In late 2023, 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).
Bridge repairs are complete on the I-5 Bridges over Leland Road, near Sunny Valley.
