Several emergency responders, including hazardous materials personnel, responded to Highway 26 westbound at the Barnes off-ramp where at least one container inside a semi-truck was leaking sulfuric acid.
The 69B exit and the right lane was blocked to through traffic for hours as crews tried to get the leaks sealed around 2 p.m.
In addition, all Tri-Met MAX trains were halted through the area, and buses were used to move passengers in the area.
For a short time police shut down all lanes of Highway 26 as hazmat crews investigated the leak at the truck.
As a precaution, personnel on scene were advised to stay 150' away from the semi-truck.
A spokesman with Tualatin Valley Fire and Rescue said responders from Beaverton police, Portland police and ODOT also worked on the problem and directed traffic.
Sulfuric acid is a highly corrosive substance that can cause harm upon contact or if inhaled, according to officials.
The investigation is ongoing.
