A portion of Cornelius Pass Road to close this weekend
Crews will clean up contamination from tanker truck spill in January
Traffic on Cornelius Pass Road will be disrupted on Easter weekend as a Washington County contractor completes the cleanup of contaminated soil resulting from a gasoline tanker spill in January.
The southbound lane of Cornelius Pass Road, between Old Cornelius Pass and Germantown roads, will be closed from about 7 p.m. Friday, March 25, through 7 p.m. Sunday, March 27. Germantown Road will be closed between Cornelius Pass and Old Cornelius Pass roads for equipment staging.
Two-way traffic will be flagged through the work area on Cornelius Pass Road. Motorists should expect long delays during this work or use alternate routes. Crews will work around the clock to complete the project as
quickly and efficiently as possible.
On Jan. 8, a tanker truck overturned into the west ditch after a crash with a pickup truck. Washington County Department of Land Use and Transportation and Tualatin Valley Fire & Rescue responded promptly, preventing the spill from reaching nearby creeks and other water sources.
At the time of the spill, there was concern that the roadway itself may have been contaminated, said Dave Schamp, LUT Operations and Maintenance Services manager. Recent testing indicates that there is some contamination under about half of the southbound travel lane.
There is no groundwater contamination, and we want to keep it that way, Schamp said. The holiday weekend was the soonest we could get all the necessary permits and crews together.
The countys contractor will remove the impacted portions of the existing roadway and underlying material for disposal. The roadway will then be replaced.
