Highway repair work fall 2018
ODOT has designed a repair to restore the highway to its preexisting condition, before movement occurred.
This repair will be over a larger area than previous work, between South Glenn Drive and South Freeman Road.
Work could take up to three months to complete. During work, traffic will be directed by flaggers or a temporary signal 24/7. Once repairs are complete, all lane closures will be removed.
In March 2017, ODOT observed cracks in the pavement on OR 213 near South Eldorado Road. ODOT used The Oregon Department of Geology and Mineral Industries, also known as DOGAMI, landslide database and conducted site investigations. Based on that research, it appears the active landslide is part of a larger group of ancient landslides originating along the southern flank of Spangler Hill.
We developed a phased approach to address the landslide and pavement conditions.
In October 2017, ODOT completed the first phase of repairs to the pavement, which was aimed at strengthening the road and temporarily repairing abrupt edges running across the highway. The repairs involved installation of layers of rocks and geogrid, a strong plastic material that strengthens the road and allows some movement.
The pavement continued to shift in the areas between where the geogrid was installed.
From January to March 2018, crews installed 40 drains below the highway that created an easier path for water to drain from the area, reducing the potential for additional movement. The drains continue to function well.
We installed instruments to measure movement of the road throughout the process. We installed additional instruments after the drain work was complete. Clackamas County continues to monitor local roads.
The instruments have shown no significant movement since March 2018. We are not anticipating any additional significant movement based on our instrumentation findings.
We will continue to monitor the highway on a long-term basis.
