Bridge Collapses as Motivation
Sometimes its useful to re-motivate ourselves. A sobering TIME magazine photo-essay reminds us why we research and try to continually improve the design process:

Julio,
You’re correct – it is a typo. The line above this should be 72R-900 = 6(720-36R). 18.13 kN is the correct result.
Colin – I drive across this bridge every day. Its looking better than that photo you posted!
