September 6: Post the junction of an Interstate and a route of a different type, of which one route ends in 0 and the other route ends in 5.

This might be the easiest day of the whole season.

Definitely one of the easiest.  This season's challenge is harder for me to find matches from my main sign picture index page than in the previous ones.  So ChatGPT and I collaborated on a Python program that parses my picture page looking for potential matches.  Here's what it finds as potential matches for the first 10 days:

Code Select Expand

Found 113 matches for endings 0 and 0
Found 95 matches for endings 0 and 1
Found 71 matches for endings 0 and 2
Found 71 matches for endings 0 and 3
Found 61 matches for endings 0 and 4
Found 177 matches for endings 0 and 5
Found 48 matches for endings 0 and 6
Found 85 matches for endings 0 and 7
Found 55 matches for endings 0 and 8
Found 45 matches for endings 0 and 9

In all of combinations, many are duplicates or pairs that aren't really at an intersection (lots of "To I-90"), but it has been really helpful to narrow down almost 20,000 table entries to several dozen.

Considering that the northbound on-ramp from I-380 intersects PA 435 and PA 507, I would say that this on PA 435 SB counts.
