PORTLAND, Ore. – The Portland Bureau of Transportation was not impressed by the salt it used on Portland roads.

In a news release, the bureau said the salt "did not provide significant improvement compared with the bureau’s standard de-icer."

The city of Seattle on Wednesday sent 11 trucks and salt to help clear snow in Portland after a historic snowfall. Eight of those trucks were equipped with plows and salt spreaders.

PBOT tested salt on Terwilliger Boulevard between Capitol Highway and Sam Jackson Parkway, Broadway between West Burnside and Interstate 405, and on Swan Island.

Despite its disappointing performance, the salt will likely get another chance. A spokesman said PBOT will continue to look for opportunities to test options, including road salt, in the future.

On Jan. 9, the Oregon Department of Transportation used salt for the first time in Portland.

Salt use in winter weather has been controversial in Oregon because of its impacts on the environment.
