Also, watch the Michigan Department of Transportation “slide” a new bridge into place.

In the world of state-produced videos, transportation departments often get some of the best material to document and feature. Infrastructure in action can be especially captivating to watch, especially when you apply time-lapse techniques to construction or demolition videos.

That's what the Utah Department of Transportation did recently with the demolition of a bridge south of Salt Lake City along Interstate 15, condensing the destruction of an overpass into 32 seconds.

Here's an alternate view condensed into 43 seconds.

Utah, naturally, isn't the only state to use video to demonstrate the abilities of its transportation department.

Last summer, the Michigan Department of Transportation used videos to show off a new bridge construction technique: the bridge slide.

That was the simulation. Here's the video of the actual bridge slide-in action for a new overpass along Interstate 96 east of Grand Rapids.
