The 417 is one of two freeways in Ottawa (along with the 416). It travels west to east through the city. On occasion an overpass bridge for the freeway needs replacing. The technique here in recent years has been to build the replacement section, or sections, near where the overpass is, and then in one weekend, cut out the old overpass and move the replacement into place. This minimizes the amount of time the freeway has to be closed in the given area around the worksite. In late October, it was done here at the Kent Street overpass. The freeway was shut down for a stretch to either side, with detour routes set up. The work took the entire weekend, but it was done in time. For some reason this has become something to watch, so bleachers were actually set up on the south side of the worksite, and a webcast was set up as well. Most of these shots from that weekend are from the south side of the project, with the exception of one. Needless to say, most of the people watching this go on were guys. I stopped by several times during that weekend and photographed things.
