Neato, I'll axe it.
Since we're on Pueblo here, I noticed that the HB has 50B following Santa Fe St. through downtown to Exit 99B, the data explorer has 50B following Santa Fe St. to CO 96, and signage (per Google Maps) has 50B merging with I-25 at Exit 98A and skipping downtown entirely.
I'm leaning toward moving it to the Interstate right now.
