These led to extensive studies of the safety of box girders and serious concern over their continued use. This was also an early use of computer modeling and a spur to the development of finite element analysis in civil engineering.

Its guardian grasp on blood and brain,
Old terrors then of god or ghost
Creep from their caves to life again;”
