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.

    A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

    Work continues on the 2.3km Mersey Gateway signature bridge project close to Liverpool in the UK. David Arminas reports on some of the construction highlights. Under construction is a cable-stayed structure with three towers that will span the Mersey River’s expansive mud flats between the towns of Runcorn and Widnes near Liverpool. Including the approach viaducts on each side, it will be 2.3km long with a river span of 1km. The main bridge deck will be reinforced concrete. The 80m-high central tower will b

    Imaginative formwork, often using modular components, is helping to shape some challenging bridges worldwide. Patrick Smith reports Traffic volumes in and around Prague have swollen massively in recent years, pushing the existing road network to the limits of its capacity. To permanently ease congestion in the Czech capital's centre, a multi-lane orbital motorway is under construction as a high capacity bypass for central Prague and to link up all the motorways and other major highways radiating from the ci
