VIDEO - Bridge demolition going wrong

June 17, 2015
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.

The Viitostiellä Mikkelissä bridge collapsed following a few blows from a hydraulic hammer to the deck, suggesting the structure was in a very poor condition indeed.

    Italian contractor General Smontaggi has carried out a successful bridge demolition project in the south of the country. Explosives were used to remove the redundant Viadotto Caffaro Bridge carrying the A3 Autostrade. The 390m long structure had been found to be unsuitable for modern traffic requirements on the route, located in Calabria. The demolition project was not straightforward as the new bridge had already been constructed alongside the redundant structure. The extensive pre-weakening work for the old bridge included cutting into the deck to ensure it collapsed downwards.

    The shocking collapse of a major highway bridge in the Italian city of Genoa has highlighted a major problem with regard to poor infrastructure condition in the country.
