While visiting my parents last week, we drove on something like 75% of a route signed in the field as "PA 29 Truck". I noticed in my own files that I have this route already listed, so I must have noticed the signs on an earlier trip. But it's apparently not in the TM database.
I checked the
usapa.csv file edit history on GitHub, to see if there used to be one listed that got deleted. Nothing. I checked the
CHM updates. Nothing.
It doesn't appear to have ever existed.
Checking your list file, I see
PA PA29TrkMac PA29_S PA29_N added on
Jan 27, 2016, the first update after the
initial commit. Maybe seeing the .list lines added/changed in the 2016-01-27 link might jog your memory WRT that specific road trip. But anyway... There's another Trk
Mac route,
PA100TrkMac, which shares the Buckeye Rd alignment.
A friendly finger-shaking here; it's always a good idea to check the HB for a route and its points before adding it into your .list -- not only to get the City abbreviation right (EG, Mac as opposed to Emm, etc.), but also the waypoint labels. PA29_S & PA29_N look like pretty safe labels, but not all truck routes connect to the parent at both ends. 
No harm done here though. It's helped us find an oddity. I've searched the forum archives as best I could and found nothing about this; if there actually is a topic for it please point me thataway.
AFAIK, there's not a topic for this specific route.
OTOH, search the forum for "truck", and...
hoo boy.CHM/TM veterans know that the best way to discuss *&^$# Truck Routes is to hold down Shift and mash a bunch of number keys.
This appears to be a route for heavy trucks to avoid a few weight-limited bridges on PA 29 near Emmaus, and looks to be around for a while as I've seen no news of plans to rebuild those bridges in the near future.
I wanna say that a good many truck routes in PA are this exact same thing. One of them did get deleted in the not-too-distant past after its bridge was rebuilt.
ISTR there being discussion on these, probably (WRT PA specifically) occurring more on the old CHM forum. I can't be bothered to look any of it up now, but I wanna say
(and I could be talking out of my tuckus here) that the idea was not to put much extra effort into finding/listing/cataloging all these routes, but to add them as we became aware of them. With a few misgivings about
that, possibly...
Is this a route that should be added to the database?
If this route existed in
March 2012 (when Tim added PA100TrkMac), AND Tim knew about it at that time, he probably would have added it.
But it's 2018 now, and Tim no longer maintains PA.
Nonetheless, Tim's M.O., at least in PA, seemed to be to include such
(temporary?) truck routes when known. So right now I'm leaning slightly toward including it, for the sake of maintaining consistency within PA.
I think
rickmastfan67 is probably the mostly knowledgeable data contributor WRT PA. Thoughts?
