Thanks for passing this along. I will need some time to get through all of it, but it should answer some lingering questions.
Re 14R, it's difficult to separate it from vanilla 14. Both are almost exclusively on one-way streets in Ponce, and 14R doesn't always refer to the same direction (sometimes it's eastbound, sometimes westbound). It looks like I combined 14 with 14R to make the routing for 14 in the HB (I didn't make an entry for 14 or 14R in my notes). I'm open to suggestions for something that may more accurately reflect DTOP's intentions. GMSV (2016) isn't particularly useful, since signage (including km posts) is spotty and occasionally inaccurate (there are several references to PR 10 in downtown Ponce).
