Slide-related road damage causes closures
Oregon Department of Transportation closed the left northbound lane of Highway 213 Friday after Clackamas County closed Eldorado Road at its southern intersection of 213 on Thursday. Both closures are indefinite and are due to worsening road conditions resulting from a large slide.
Drilling began Monday on the highway as part of the second phase of work to remediate the effects of the ancient slide, and with it, more movement of the cracks is likely; but ODOT assures drivers that the road remains safe.
The speed limit in this area will reduce from 55 to 45 miles per hour for the duration of repairs, according to ODOT. Between the hours of 8 a.m. and 2 p.m., drivers should expect 20-minute delays.
This is the second phase of work which involves installing horizontal drains below the highway to help drain water from the landslide area. This is expected to create an easier path for water to drain from the area, which reduces the potential for additional movement, according to ODOT.
The drain installation is expected to take several months.
The cracks on Eldorado have been present for almost a year, according to Clackamas County Project Manager Vince Hall.
"In the last year, the County hasn't seen much movement," Hall said. "In the past week, the cracks have grown about 1-inch wide and the vertical displacement of the cracks have increased about an inch."
The intersection is located slightly north of Mulino, uphill from the highway, in unincorporated Clackamas County.
Local residents are encouraged to use Union Hall Road as a detour route.
Hall expects ODOT's project to help retard the ground movement on the Spangler Hill Slide, where Eldorado Road is located. County officials will monitor Eldorado Road closely during ODOT's repairs.
Detour signs will be posted and area residents will be kept informed about any changes to the status of Eldorado Road.
To talk to ODOT about the landslide, area residents are invited to attend a project open house on Tuesday, Feb. 13 from 5 to 7 p.m. at Arrowhead Golf Club's Payne's Stewart Meeting Room.
