VIDEO: Explosive bridge demolition in Southern Italy

February 15, 2016
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 charges were timed in such a way as to break up the bridge deck first and allow those pieces to fall, before a second round of charges detonated to bring down the supports. The explosives for the supports were also placed very carefully to ensure that in falling, they would not strike any part of the new bridge.

    Financial troubles for Brisbane's new Airport Link overshadow its construction success – Adrian Greeman writes. Political argument and legal dispute is likely to rage for some time yet over the bankruptcy of Australian road operator BrisConnect, which went into receivership this February with A$3 billion in debt. Toll paying users for its new Airport Link have been less than half the predicted numbers since it opened in July last summer. But if its nancial engineering is being questioned, the same is not t
