I've seen this before on the Delaware Memorial Bridge: Falling ice from the suspension ropes and tubes case them to shut down the outside lanes.  Thus, 2 lanes are open in either direction.  Unlike some of the past incidents, weekday, winter closures don't tend to jam up traffic all that much, especially since people aren't necessarily slowing down to see construction work or anything.

Do other suspension, cable stayed, or cantilever bridges have a problem with this?

Yes.  East River bridges in NYC do...but I don't think they shut down outside lanes to deal with it.

Remember that this wasn't a snow storm though...in DE, it was all sleet and freezing rain...so this was an unusual event.

They still had some snow, especially in the Wilmington/South Jersey areas near the bridge.  Then combined with the thawing and refreezing, making the icicles, the long icicles occur.  During the next thawing is when the icicles fall, and causes the lanes to be shut down.
