Fractured  eyebar member from the    Pt.   Pleasant   Bridge.  The eyebar contained an initial flaw, due to stress corrosion, one-eighth of an inch long.

The eyebar then fractured in a brittle manner with the crack extending rapidly from the initial flaw.  The entire 1700-foot long bridge collapsed in less than 60 seconds.
