One thing that didn't make it into the story: "Surcharge."
No, that's not the fee that TriMet plans to charge to spectators trying to get a good look at the pour.
It's the engineering term used to describe a huge pile of dirt being used to compress the earth at the future location of the west-end abutment, where the cable-stayed bridge will essentially begin its reach from the South Waterfront.
"We're compressing the earth and driving out any problems with the settlement," said Robert Barnard, the Portland-Milwaukie Light Rail project's director.
