text: * In 2013, six months prior to opening, the East Span of the Oakland Bay Bridge failed during testing. Catastrophic failures occurred in shear bolts in the span, after only two weeks of service, with the failure attributed to embrittlement (see details above).
  * In the City of London, 122 Leadenhall Street, generally known as the Cheesegrater, suffered from hydrogen embrittlement in steel bolts, with three bolts failing in 2014 and 2015.  Most of the 3,000 bolts were replaced at a cost of £6m.
