14. Gasconade Railroad Bridge

Location: Gasconade, MO

Year of Fail: 1855

A rather blatant oversight—temporary trestle work was never replaced with the permanent structure—during the inaugural run of the The Pacific Railroad in 1855 caused this wooden rail bridge to collapse, killing over 30 people and injuring hundreds. The train that plummeted from the bridge was full of special guests and dignitaries that the governor had invited to celebrate the new route to the state capital.
