'Hospital Road' just south of the 'SprBroPkwy_MtP' point should have one, due to the on/off ramps to the Sprain Brook Parkway there (& the Sprain Brook Parkway having a point already on that road too).

Also would recommend a point @ Ardsley Road (just north of the 'FortHillAve' point), as it connects over to the Bronx River Parkway Exit 11.
