Project-Details





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 so the southwest Oregon region can remain connected and recover after a major earthquake.​​


Impacts

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 with short delays to full closures and some out of direction travel.

Meetings and Events

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

Schedule

This first bundle of bridges will be repaired in the Grants Pass area in 2021 through 2023. Those bridges include: 
  • I-5 Exit 80 Glendale bridges,
  • I-5 Exit 58 bridges at north Grants Pass interchange and,
  • I-5 bridge over Hillcrest Road.
The first set of bridges are complete on the I-5 Leland Road bridges at Sunny Valley​.

It's anticipated the first slopes will begin in 2022.

Instead of one large project, this project is split between slopes and bridges for cost efficiencies.

Details

About

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.

Location

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

Cost and Funding

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

Contractor

​H.P. Civil of Salem, OR is the contractor for the first bundle of bridges.

Benefits

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

Lifeline routes will be strengthened so freight and recovery materials can be transported in and out of southwest Oregon.

Triage is in the title of this project because it takes the easiest, least expensive slopes and bridge to repair and maintain critical connections after a major 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 planned to begin in January 2021 at the I-5 Exit 80 Glendale Bridges, and later at the I-5 Exit 58 and nearby I-5 Hillcrest Drive bridges.

​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).
Bridge repairs are complete on the I-5 Bridges over Leland Road, near Sunny Valley.
