There’s no easier way to make thousands of people mad then to screw up traffic for an extended period of time. Road construction can also be extremely dangerous for road crews working throughout the world. It seems like I read a story about a construction worker killed by a motorist every single day, so whatever it takes to lower that number can only be a good thing.
Modular and pre-fabricated construction is growing popularity on the commercial and residential side of the industry, put it may be even more so on the infrastructure end, and for good reason. By completing major portions of the work off-site, the existing conditions are only affected for a minimal amount of time. In the video below, you’ll see a 230 feet long tunnel (70m) be installed under a highway overpass in just 3 days. The existing overpass had to be demolished and re-built in that same time period, as well. That’s not something that can be accomplished with a traditional cast-in-place method. With the tunnel already built, it merely had to be pushed into place.
The tunnel spanned under the A12 highway in the Netherlands, which heads towards Arnhem. Dutch construction company Hejimans performed the job through an impressive thunderstorm, as well, which is shown towards the end of the video. This isn’t the first highway overpass to be removed and replaced in one weekend either, just last year a Chinese construction company removed and replaced a very large overpass in just 43 hours.
