TN: I-26/US 23 Kingsport TN Welcome Center

[Markkos1992]

Should we have a I-26_U point here?  It looks like in theory someone can stop here and turn around to end up in the other direction.

I'll second this.

But disagree with the 'label'.  Maybe go with the following instead?

Mainly basing this on how I named the one on I-10 in FL that you can access going both ways and U-Turn at if you so choose.

[Markkos1992]

Yeah, I like the TNWelCen label better.

I looked at I-476 at the Allentown Service Plaza, and it looks like you are still forced to stay in the direction you entered in, but I am uncertain based on GSV.

SD has one of these as well in Chamberlain, and there's no point there now (will start new thread).

If we're doing this kind of thing, I expect there are many more.  Maryland House and Chesapeake House and the Delaware Service Area come to mind as places where a driver can switch directions on I-95.

[Markkos1992]

Yeah, at least adding the Biden Welcome Center easily eliminates a shaping point.  https://github.com/TravelMapping/HighwayData/pull/6780

Well, if they are a full interchange, and you can change direction and not forced to keep going the same way (Sideling Hill Service Plaza on the PA Turnpike comes to mind of one that serves both directions, but you're forced to continue the way you were going originally), they IMO should be in the file for the route.

Fairly certain that the Allentown Service Plaza on the NE Extension (aka I-476) does still strictly segregate NB and SB traffic so you can't make a U-turn. There's a gate in the fence so that in emergencies PTC can allow traffic to reverse direction, but that gate is always closed except in true emergencies.

I second the TNWelCen label.

Likewise the travel plazas on the Garden State Parkway now named for James Gandolfini (fka Pascack Valley / Montvale), Jon Bon Jovi (fka Cheesequake), Judy Blume (fka Monmouth), Celia Cruz (fka Forked River), Frank Sinatra (fka Atlantic), and Toni Morrison (fka Ocean View), and the GSP's Shoemaker Holly Picnic Area.

If a point is added, I-26_U is the correct waypoint label per the manual: https://travelmapping.net/devel/manual/wayptlabels.php#other

The interchange is not "nothing more than a U-turn ramp".

Wrong, it would fall under the "For a park or other non-commercial point, abbreviate the name as if it were a named highway" one above it.

Signage at the ramps clearly say 'Welcome Center'.  That 'U-Turn' one if for ramps that are literately just U-Turns (similar to the ones you can find on US-22 in PA).
