This may only work for bridges that cross railway lines but I like it anyway. Rather than taking several years and massive traffic delays to replace a bridge, Boston pre-fabricated it and slid it into place over the course of a weekend.

Wish I could download the video but the Times has it encoded somehow. So check out the article and click on the video at the top to see it being put into place.
