Structural problems have caused a recently constructed bridge in Nepal to deflect, even before it has been officially opened. The bridge links Eastern Lamjung and Tarkughat and has dropped some 150mm. There is concern that the bridge may collapse, although the local government officials still plan to have the official opening for the 75m long steel truss bridge without further repairs or. The structural issues are likely to have been caused by high water flow rates, which could have affected the formwork in place during the pre-casting process. Bridge scour is a key problem for bridges in Nepal due to the high velocity water flow rates in this mountainous country.

    Explosive demolition has been used to remove an old highway bridge in Pennsylvania. Some 90kg of explosives were used to blast the pre-weakened steel structure of the 87 year-old Masontown Bridge. The redundant steel truss structure lay just 3m from the new bridge now carrying Route 21 over the Monongahela River and connecting Masontown with Monongahela Township. The location of the explosives and the pre-weakening work carried out however meant that the old structure, built in 1925 and upgraded in 1933, fe
