(Portland, OR) -- A sewage overflow near the SW Beaverton-Hillsdale Highway is now stopped. It took crews with the Portland Bureau of Environmental Services five hours Saturday night to stop the overflow after an estimated five-thousand gallons of sewage went into the street. Some of that overflow also reached Fanno Creek, so the public is asked to avoid contact with water downstream of the area. Officials say wet wipes and grease from an apartment complex caused the issue.
