I was wondering about a railroad bridge in the city of Yakima, Washington. I don't really know where it goes, but it branches out directly East of the depot downtown, and crosses under the I-82. It basically follows G st. from the mainline and appears to be a very minor branch line. Just East of the Interstate, the bridge is quite unique. The approaches to the three span bridge (the one on the other side of the river is longer) are trestles made in the same process as wooden ones, but made of steel I-beams driven into the ground. There could even be old rail sections in the mix. I pass under it when I go for bike rides and it is remarkable how it looks like a wooden pile-driven approach from far away.

Would anybody have any more info on this bridge?

Thanks
