OR 213: Highway repairs in Mulino

Construction Phase

Region 1: Portland metro and Hood River County (Molalla, Clackamas)


The second phase of repairs is underway on Oregon 213 (Cascade Highway South) in Mulino where a large crack across the highway was discovered in March 2017.

Impacts

Construction Impacts

One lane is open in each direction. Crews completed pavement repairs early morning Friday, Feb. 2.

We will continue to monitor pavement conditions and will close lanes again if needed for safety. Even after repairs, travelers should expect pavement will continue to move as the landslide moves. 
 
An enforceable speed reduction to 45 mph is in place. 

Clackamas County has closed Eldorado Road at its southern intersection with OR 213 as of Jan. 18.

Meetings and Events

Thanks for attending our open house on Feb. 13, 2018!

You can find the handout and displays shared at the bottom of this page. 

Schedule

Phase 1: ​Repairs for the highway surface were complete in October 2017.
Phase 2: ODOT began work in Janaury to install horizontal drains below the highway to help drain water from the landslide area. Drain installation is scheduled to take several months.

About

Pavement has shifted at the site of an ancient landslide that reactivated last winter on Oregon 213 – Cascade Highway South – Near South Eldorado Road in Mulino. 

ODOT developed a two-stage plan to address the landslide and the resulting pavement damage. Crews will return to project area this winter. 

View the project fact sheet​ from Jan. 26, 2018. 

The first phase of repairs is complete --
Beginning August 23, crews will excavate 5 feet down from the roadway to repair several sections of the highway near South Eldorado Road. 

An estimated 3,000 cubic yards will be excavated – enough to fill 200 single dump trucks. 

The contractor will insert layers of rock and geogrid, a material used to reinforce the highway base, and pave the surface.

The crack across the highway developed as an ancient landslide reactivated during record-setting rains over the winter. Later this year, ODOT plans to install horizontal drains below the highway to help drain water from the landslide area. 
​​
The second phase of work began in January 2018 --
The second phase of work is scheduled for this winter and will address the landslide. The contractor will install horizontal drains below the highway to help drain water from the landslide area. Illustration showing the drains installed below the highway.

In a landslide, water acts as a driving force. Installing drains creates an easier path for water to drain from the area, reducing the potential for additional movement. 

The installation process for the drains creates high water pressure, a source of landslides. The contractor will work from below the highway to install drains while monitoring the slide area and minimizing movement. Some movement of the slide area is expected.

Additional Information

​Clackamas County has closed Eldorado Road at its southern intersection with OR 213 as of Jan. 18. Cracks in the road began growing over the past weekend. 

The widening cracks appear to be related to a large slide impacting OR 213. The county will continue to assess the status of Eldorado Road to determine what action is needed to reopen the roadway.  

A detour route has been established; all local residents are encouraged to use Union Hall Road as an option. Detour signs will be posted and area residents will be kept informed about any changes to the status of Eldorado Road.

For questions about Eldorado Road, please contact Ellen Rogalin from Clackamas County at 503-742-4274.

The county has provided a handout for residents with resources. View the handout. You can also view a "Homeowner's Guide to Landslides" and a fact sheet​ about landslides in Oregon.
