2002 CLK55 Serpentine belt failed with 10k miles on it?



I was driving yesterday and steeped on the gas a little from a stop sign. I hear this whooshing sound soon after. I pop the hold and my serpentine belt is starting to shred. I'd say its still 75% intact and on all the pullies etc. What is odd is that this belt was replace in Fec 2018 or 10k miles ago. I doubt it is the belt so I am wondering what else could have failed to cause this? An idler pully or something? Also, I have a shop 3 miles from my house and I'd rather not tow it. Any thoughts on how risky it is to drive that far? I am thinking if it comes off I'll know right away wit the 'visit workshop warning.
thanks
