How many workers does it take to get back under control a concrete buffer that won’t be tied down? Quite a lot, apparently, as this video shows. The real question is, which cement-head lost control of his buffer in the first place?

How many workers does it take to get back under control a concrete buffer that won’t be tied down? Quite a lot, apparently, as this video shows. The real question is, which cement-head lost control of his buffer in the first place?
The show - nearly 5% bigger than the record set in 2020 - will feature 1,800 exhibitors and 150 education sessions during its run from March 14-18, 2023.

As vice president of Canadian barrier specialist QMB, based in Laval, Quebec, Marc-Andre Seguin is sanguine about the future for moveable barriers.
On the one hand, it looks good. The oft-stated advantage of moveable barriers is that the systems are cheaper to install than adding a lane or two to a highway or bridge. Directional changes to lanes can boost volume on a road without disrupting tra
Loosely defined, an interchange is a road junction that uses grade separation and ramps to allow at least one highway to pass through the junction without intersecting another highway.
A simple definition for many apparently complex interchanges worldwide.
The thing about a road interchanges is that, as a driver, you fail to see how large – or complex – the structure is. This compilation, called the top 10 craziest intersections, shows you what you miss as you hurtle through an interchange - from the UK and France to the US and over to China and Japan.
A bridge demolition job went spectacularly wrong in Finland recently. Luckily for all concerned, there were no casualties, but it could have quite easily been a different story. A demolition contractor was using an excavator fitted with a hydraulic breaker to break up the structure, but the work was carrying on despite live traffic flowing on the road under the bridge.
Note too the behaviour of drivers on the route after the initial collapse.
This video came just as the European Demolition Association headed to Finland’s capital Helsinki to discuss best practice.
