Watch the video of an explosive highway bridge demolition from the US. A demolition contractor recently removed an old highway bridge in Missouri using explosives. The bridge spanned Interstate 44 but had to be replaced as it no longer met requirements. Having been built in 1960, the bridge was 127mm (5”) too low to meet the current minimum height specification of 4.877m (16’) while it also required repairs to its deck that would have proven costly to implement. A new bridge will be built that meets the height requirements so as to allow sae passage of vehicles underneath. This new structure will also feature additional capacity with extra lanes as an expansion of a nearby industrial area is planned.
