Where did Jason die?

In the story "The Boy Who Wrestled With Angels," we learn that Jason collapsed on the loading dock of the Food Star supermarket. He was eventually hospitalized after shooting heroin into his veins. Gretel relates that Jason had noticed strange sensations immediately after the heroin entered his bloodstream. He collapsed on the loading dock and was found unconscious by his girlfriend, Terry LoPacca.
Jason had been abusing drugs for a long time. He had apparently been awarded a scholarship to Harvard but could not attend. At twenty, Jason worked in Food Star's deli department, worrying about how he would help pay his mother's medical bills and the mortgage.
Jason's drug habit eventually killed him. In the chapter, we learn that Jason died beneath an overpass, where he had been getting high from heroin.
