Urgent No Pwr Steering

[rvnmaniac]

A mile from work i made a right hand turn and all of a sudden i have
no power steering and all kinds of lights on the dash came on, pwr
steering light, battery light, ABS, and a few more. Facing the engine
it's the upper left pulley that came off of it's belt. What ever bolt
holds that pulley on is gone and the pulley may be stripped. The belt that this pulley was on controls what, other than the obvious right now which is the Pwr Steering? The other belt is okay. Trying to figure if i can drive it
about 5 miles to a service shop or do i need to have it towed away. Any
help would be appreciated. The belts were recently changed but the work was performed in New Jersey so i can't take the car back there. I'm thinking the bolt for that pulley may not have been torqued properly and came loose.
THANKS
