While traveling w/b on I78 into Pennsylvania I noticed my car suddenly veering to the left. I stopped at a toll booth to proceed to the next exit to check on the problem and as I accelerated out of the toll booth the car began to fishtail wildly. After being able to bring the car under control I pulled off to the shoulder expecting, from the sound of the scraping metal, to find a blown tire. When I checked on the r/r tire I noticed it seemed to have collapsed and that the lower control arm had broken from the frame of the car leaving the car inoperable. I had the car taken on a flatbed to the nearest Nissan dealership.
