A new bridge over I-70 at Pecos Street in Denver was successfully rolled into place this weekend. While the project took a weekend to complete, you can watch it in 60 seconds – with none of the traffic delays.

The demolition of the old Pecos Street Bridge, and the placement of the new one was quite a spectator event with the Denver Post reporting more than 1,000 people visited a designated viewing area throughout the weekend.

There were hundreds more who streamed the project online. Rather than constructing the bridge in place, the whole thing was assembled off-site and then rolled into place. Quite the feat of civil engineering.
