I agree with the westward extension of NM 500 to I-40. In my queue.
Before submitting it, I'll browse the rest of the functional class map (thanks for the link!), and catch up on Transportation Commission minutes, to look for other needed updates. A minor change I spotted -- looks like a short truncation of NM 501 in Los Alamos, from its old north end at Ridgeway Dr. to its new end at Sandia Dr.
