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. The goal is 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 or full closures with some out of direction travel.

Meetings and Events

A drop in open house was held October 20 in the area of Hillcrest Road for area neighbors and interested community members. 

Our on line open house is still open for viewing:

Schedule

Bundle #1: 
Crews are scheduled to begin the first of two seasonal closures of the I-5 Hillcrest bridge.
  • The first is Oct. 31, 2022 thru May 23, 2023.*
  • The second is Oct. 31, 2023 thru May 15, 2024.
* - Original opening date was a week earlier, May 15.

Local traffic will see a full closure of Hillcrest Road. A detour will be signed using 9th Street, Savage Street to Beacon Drive.

The full closure is required due to narrow width of Hillcrest Road and due to the nature of the work on the bridge foundations and horizontal beams. 
The needed two seasons are to avoid a single access during fire season. 

A project open house was held October 20, 2022 for interested community members.

Other Bundle 1 Construction:
  • Crews are nearing completion of the work on the I-5 Exit 58 bridges in north Grants Pass.
  • The first set of bridges are complete on the I-5 Leland Road bridges at Sunny Valley​.
  • Improvements are complete on the I-5 Exit 80 Glendale bridges.

Bundle #2:
This Bundle is complete.


B​undle #3: 
This bundle bids in January 2023 with construction anticpated now in early 2024.
It replaces 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.

Slopes: ~$13.3 million- this phase is currently in development.

Historic slopes have been tested for stabilizing with construction expected in 2023. 

Repairs include rock buttress, anchors, retaining walls and drainage improvements. 
They are located at:
  • Interstate 5 in Jackson County at MP 5.2, MP 10.3 and, in Douglas County, 114.6.
  • Oregon 140, east of White City at MP 22.1

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.​
  • Sutherlin Creek Bridge on Del Rio Road in Douglas County.

Cost and Funding

$~53 million is earmarked for this project by the 2017 Keep Oregon Moving act passed by Oregon Legislature. Other funding has been secured for this project as well.

Contractor

  • ​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.

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 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?

​​This project will make southern Oregon/Rogue Valley more resilient prior to a seismic event, including a Cascadia Subduction Zone earthquake.

Bundle #1
​Contractor HP Civil is nearing completion of the I-5 Exit 58 bridges.

The nearby I-5 Hillcrest Drive bridge is scheduled for work Oct. 31, 2022- May 23, 2023, and again Oct. 31, 2023-May 15, 2024

There will be a full closure of Hillcrest Drive under the I-5 structure. Local traffic detour via a signed detour route using 9th Street and Beacon Drive I-5 undercrossing.

Josephine County and Grants Pass are also planning to improve both 10th Street and Hillcrest Road.

Bundle #2:
Nearing completion in November 2022
  • Little Butte Creek Bridge at MP 7.75 
  • Schoolhouse Creek Bridge at MP 8.46 
  • Lick Creek Bridge at MP 9.15, and
  • North Fork Little Butte Creek Bridge at MP 15.44

The Sutherlin Creek Bridge on Del Rio Road, northwest of Roseburg, is the last bridge in this bundle. There will be no closures. 


Bundle #3:

​Rogue River Highway Bridges:
In 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).
Slopes: ~$13.3 million- this phase is currently in development.

Historic slopes have been tested for stabilizing with construction expected in 2023. 

Repairs include rock buttress, anchors, retaining walls and drainage improvements. 
They are located at:
  • Interstate 5 in Jackson County at MP 2, MP 5.2, MP 10.3 and, in Douglas County, 114.6.
  • Oregon 140, east of White City at MP 22.1​
