The bridge is fracture critical, meaning if any tensile element fails, the bridge could collapse. A crack in a steel cable is very serious and called for the bridge to be closed.
The bridge has reopened.

QuoteSwank Construction finished the replacing the bridge's main support cables and temporary supports have been installed for the transition.
"The bracket that was holding up the temporary support system for the cables failed," says Cheryl Moon-Siriani Executive for District 11 of PennDOT.
It was a single failure but Moon-Siriani says it put in question the delicate engineering balance of the bridge, "A problem on one cable could cause additional cables to take on more loads. We don't play with risk when it comes to 25,000 vehicles a day using a bridge. If we felt there was any risk of safety, which we did, then we shut the bridge down."
PennDOT's engineers worked through the night to come up with a solution to the problem and have decided to go with a different support system.
Meh. It's just cocaine.
