NY: US 9 point request

[Jim]

I'd like a point on US 9 a little south of I-87(13) at Malta Ave.  This will allow me (in a couple of my extra lists) to map my usual route to get between NY 67 west of Ballston Spa and I-87 north of that area.  I rarely have need to take US 9 further south than that little stretch.
