Construction on the Colorado River Bridge — part of the Hoover Dam Bypass Project — began back in '05, but it's finally at a place where it's ready to show off. It's supposed to be finished by the end of next year and, when it is, it'll bridge the gap of the Black Canyon, stretching nearly 2,000 feet and standing 900 feet over the chasm. That 1,060-foot, concrete twin-rib arch you see there is almost finished and will support the bridge.

You can even check in on the construction in real-time via a webcam installed by the bridge. See more in the gallery below.
