This website used to show you the current color of the Tilikum Crossing Bridge in Portland, OR.
Tilikum Crossing's lights are supposed to change color based on the temperature, speed and height of the Willamette River below.
I had a theory that they never actually turned on the color changing lights, and that they'd just left it on the same shade of green for a few years. Apparently the color does change!
However, the webcam I was using to get the color of the bridge changed from using Youtube to another streaming provider, and I haven't been able to get it working with the new provider yet.
Until I get it fixed, the site will say 'green', which is the color the bridge usually is during the winter anyway!
