Resurrecting this thread because I actually now agree with mapmikey on the I-66 "76" point.
In my opinion, the "76" point should just be put under VA/DC. VA/DC on both I-66 and US 50 should be moved to the southeast slightly. We can debate on whether there should be a GWPkwy point synced with I-66, but the I-66(76) point on US 50 should be put under VA/DC as well.
In DC, I would still change US50 on I-66 to US50_E and I-66 on US 50 to I-66_E.
In the meantime for US 50:
1. NBraSt should be BraSt_N. SBraSt should be BraSt_S. (in Winchester)
2. FairOak should be changed to FairOaks. FairOaksMall IMO would go against the three-word rule since Mall is not a road abbreviation.
3. FairPkDr should be FaiParkDr.
4. CHRd should be CouHouRd since Court House Rd is two words here.
5. QueenSt should be QueSt.
Also for VA 110, is PenAccRd correct?
I made all the changes. Here is what I did with US 50/I-66 at the Potomac River:
US 50: Made 76 an alt name for the VA/DC point
US 50: Deleted the I-66(76) point
I-66: Moved the 76 point to sync with the GW Pkwy point, made 76 an alt name for it
In DC, I added a point on both I-66 and US 50 where they diverge before reaching Virginia
While making the DC/VA line point more accurate per the post above, I also made the US 50 and I-66 coordinates slightly different so that there would be no concurrency at the boundary line. This will almost certainly create a FP NMP
