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

Schedule

Bundle #1:

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.

Crews are improving the I-5 Exit 58 bridges in Grants Pass. Completion estimated fall of 2022.

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 15, 2023.
The second is Oct. 31, 2023 thru May 15, 2024.

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 width of Hillcrest Road and due to the nature of the work on the bridge foundations. The needed two seasons are to avoid a single access during fire season.

Bundle #2:

This Bundle is scheduled for completion in October 2022.

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.

Crews will be working under the Del RIo Road bridge over Sutherlin Creek in Douglas County. There are no lane closures scheduled for the Del Rio Road improvements.

Bundle #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.

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

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 Eugene.
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.

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 currently working on the I-5 Exit 58 bridges.

The nearby I-5 Hillcrest Drive bridge is scheduled for work Oct. 31, 2022- May 15, 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 October 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 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).

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.
