- GA236 also has a partial interchange with I-85 HOV lanes (no ramps to general lanes). There's no corresponding point on I-85, so I left it out.

It must be a reality new 'interchange' for it not to be in I-85's file.  Just so you know theFXexpert, we do normally include these.  Most of the time, we just estimate an exit number (if none are posted) for these types of interchanges.

GA-236 should most defiantly have a point there for I-85.

So, I'm thinking of making a point for GA-236 in I-85's file tentatively as '87A' since GA-400's exit is 87 (well, at least going NB on I-85 it is).  Plus I'm thinking that GA-400's point should be recentered some, especially since it was acquired from before the 'missing' ramps were added there.  I'll get the changes done to this later tonight, and then you can copy the coordinates into the GA-236 file.

Alright, I-85 fixes here are done.
https://github.com/TravelMapping/HighwayData/pull/618

Also quickly added in a new interchange I spotted on GA-400/US-19, 4C.

Submitted my fixes: https://github.com/TravelMapping/HighwayData/pull/627
I also took a crack at adding names to the remaining bannered routes.

- Google Streetview images from June 2015 show GA125 ending at US41 (Perimeter Rd). Has it been extended?

It appears to have been truncated there per GDOT (http://www.dot.ga.gov/DriveSmart/MapsData/Documents/CountyMaps/Lowndes.pdf). This is a recent change I guess because it was GA 125 for as long as I can remember.

In GA52 Alt (Chatsworth), "GA 255" should be "GA 225".

Just found this successor site to the old CHM site today.  I always wanted my home state routes included, but there are so many I guess it just was delayed.  For reference, I live in Atlanta GA area and have loved maps and roads for all 39 years of my life.  I've travelled all over the state in an effort to visit all 159 counties.  As part of that love, I found an e-mail address for the GA DOT and got a file listing GA state highway mileages by county back in 2013.  It didn't show all of the overlay mileages, but I was able to compare to both the official state map and online detailed county maps to build an Excel file of mileages for all Georgia routes.  I'm happy to use that file and my own personal knowledge to validate the Georgia state highway development.  I know all of the overlays will make this a challenge.

Are you planning to map all of the routes and just accept the high number of overlays with both US highways and other GA routes?  I'd suggest doing all the routes and letting the overlaps fall where they may for ease of documenting and maintaining updates in the future.

In addition, you initial question about 120 is valid.  The DOT rerouted a bunch of routes around Marietta a couple of years ago.  GA 120 now follows the old south loop and a new designation, GA 120 ALT, follows the north loop.  They have never updated the interstate signs, most likely because the state is trying to slowly update all the interstate signs to the new font.  To add to the confusion, a new designation of GA 3 Conn was given to Roswell Rd. from US 41 east to the point where the loops join.  Roswell St. through downtown Marietta is no longer a state highway.  In addition, Google doesn't show this, but they moved GA 5 off of Cherokee and Church St. and instead routed with US 41 and GA 120 Alt around the downtown square.

I appreciate the feedback. Google's street view confirms the routing of those routes is just like what you described and I will stick with that.

Yes. This is exactly what I plan to do.

Routes 150 -199 have been posted incrementally the past couple weeks.

343/482 (71.2%) wpt files are complete.

- Reroutes of GA 195 and GA 196 required new points on US19 and US84 respectively. See -> https://github.com/TravelMapping/HighwayData/pull/935
- I also found GA 162 Conn and added that.

GDOT removed the GeoTRAQS page from their site and I had to dig to find the same data here -> http://www.arcgis.com/home/webmap/viewer.html?url=https%3A%2F%2Fegis.dot.ga.gov%2Farcgis%2Frest%2Fservices%2FSTATE_ROUTES%2FMapServer&source=sd

All of the 3-digit routes are drafted with the completion of 100 -149. Only 2-digit routes remain.

388/482 (80.5%) wpt files are complete.

Some notes on this set:

- GA119 and 144 are mostly inaccessible with streetview within Fort Stewart. There is one section of GA119 that appears inaccessible to the public. GA144 is signed and publicly accessible within the base and GIS says both routes are continuous through the base. I didn't put many visible waypoints inside since the tank trails are off-limits.
- GA136 has large switchbacks around Trenton. The shaping is within tolerance, but I'm not sure if it would be a good idea to shape them for better distance approximation.
- GA138 may have been extended past US78 to GA11 in Monroe, but I can't definitively tell with streetview.
- GA142 is signed east-west for its entire length but mile marker 0 is located at the southeast end of the route. I have ordered the points as if it was east-west for now.

Other notes for other things/outlook:
- I think I got the idea of how the SVG shields work, so I tried to make the GA shields with some code from Wikimedia Commons. -> https://github.com/TravelMapping/Web/pull/118
- Sugarloaf Pkwy in Lawrenceville looks like a good candidate for select named freeways. US29/GA316 could use a waypoint at it regardless. I didn't put a point there when I did GA316 since I didn't want to break the concurrency.
- GA56 Spur in Augusta appears to have been deleted. US1, 25, 78, and 278 will need that point changed to DouBarPkwy
- Cleveland Bypass: Phase I recently completed -> http://www.nowhabersham.com/first-phase-of-cleveland-bypass-opens/ US129 will need a point at the south end.
- Avalon Bypass (GA17): was supposed to be complete last spring, but streetview still shows it incomplete as of July.
- Rome's west bypass is signed as GA1 Loop but there doesn't seem to be enough recent streetview to tell if it's contiguous or not with the rest of GA1 Loop anywhere.

Live on the site and working, as far as I can tell.

If you want to make small changes like this, go for it man!  I have no problems with that. ;)

Routes 75-99 are all up now.

412/483 (85.3%) wpts complete.

System mileage is at 8968.67 miles with many lengthy routes still left to plot.

Routes 50-74 will be in the next set.

Routes 25-49 are up.

461/485 (95.1%) wpts complete.
System length over 13,000 miles now.

The last set will have 1-24 and will also address some datacheck errors/false positives. After that, I would like to have it promoted to preview.

Note on GA28 (the Augusta segment): It is signed east/west but the mile markers start at the southern end. The Pine Mountain segment is signed north/south with mile marker agreement. So, to also keep consistent with the Pine Mountain segment and the SC28 files, the Augusta segment is arranged as if it were north/south.
