1. I left the endpoint I-44_W name copied over from BL I-44 so anyone with the old point would have a broken file. Now that I see "I-44" is not in use, I'll make I-44_W the hidden name.
2. The I-44BL_E point is "off" because I was not sure how the current intersection is set up. Right now it's in the middle of what looks like a triangle on Google Maps. On Mapnik, however, this point is now to the north of the intersection, because MO 72 was made the thru route coming from the interstate and BL I-44 has to turn. Since there are no recent-enough satellite views, I'll move the point southward to the intersection as seen on Mapnik.
