Over the last two weeks, a tall, red tower crane joined the Portland skyline on the Willamette River. Rising almost 300 feet from the recently-constructed West Tower pile cap of the Portland-Milwaukie Light Rail Bridge, the tower crane will work through the summer on bridge construction. As of July 1, the bridge has been under construction for one year and is 41 percent complete.

Tower cranes can “build themselves” in a manner of speaking, by inserting sections near the top to grow their own height. That’s precisely what this one did—watch this timelapse video on the project Facebook page and at about 40 seconds in, you’ll see the section lifts that make the crane shoot up!
