 From I @-@ 190 exit 20 , NY 324 runs in a more southeasterly direction , serving as the main commercial strip on Grand Island , before it overlaps I @-@ 190 in order to cross the Niagara River . It parts company with the Interstate Highway on the other side of the river at exit 15 , where it turns north to parallel I @-@ 190 on Kenmore Avenue . After 250 yards ( 229 m ) , it veers east onto Tonawanda 's portion of Grand Island Boulevard for 0 @.@ 5 miles ( 0 @.@ 8 km ) to a junction with Sheridan Drive . The latter carries NY 325 , a 1 @.@ 42 @-@ mile ( 2 @.@ 29 km ) route that begins at NY 266 on the banks of the Niagara and passes through a commercial and industrial area of the town of Tonawanda . NY 324 takes on the Sheridan Drive name here and assumes a more due easterly course across northern Erie County . Though the street is signed as a state highway on both NY 324 and NY 325 , most residents simply refer to this road by its local name .
