I was surfing around usends.com recently, and came across the page for
US90.
If gives a good description of the ambiguity of the signage in the field, which we can also see in GMSV.
I remembered this being a bit questionable either when I was drafting usatx or doing the Texas cleanup a few years back... Can't remember if I actually changed the file
(probably not?) amidst all that, and with the CHM forum no longer online, I can no longer check & see.
I decided to have another look at the sources listed on our credits page, and all are in agreement:
It appears that on paper, US90 still ends at its historic terminus, I-10BL, for a slightly longer route.
Shapefiles:
https://tnris.org/data-catalog/entry/txdot-roadways/These files show US90 extending all the way to I-10BL.
County grid map:
http://www.dot.state.tx.us/apps-cg/grid_search/_includes/countymapbook/Pages/1294.pdfStatewide Planning Map:
https://www.txdot.gov/apps/statewide_mapping/StatewidePlanningMap.html(This page doesn't work for me in Firefox, but does work in Chromium & Google Chrome.)
And finally, the TXDOT designation files:
The
US 90 file itself is inconclusive: changing from a terminus in Van Horn to a terminus in Van Horn may not have merited a change in description. OTOH, see TX 54:
http://www.dot.state.tx.us/tpp/hwy/sh/sh0054.htmThis acknowledges US90 already being in place at this location for TX 54 to be extended along it.
(As for SL 519, that was later redesignated as I-10 BL.)
This all would mean a 3-block extension in the HB. TX54 would stay as-is, yielding a short concurrency.
A downside is, those of us without that segment of TX54 marked would lose their 100% clinches. Sorry, Oscar!
