Dupont Court is two blocks North of 144th of Center on the West Side of the street.  If you are going South on 144th street from Pacific Street, Dupont Ct will be on your right side before you hit Center Street.  If you are going North on 144th street from Center street, you will need to make a u turn at the second set of lights since there is a road island that won't let you take a left to enter Dupont Ct.
