VA/WV US 50 not lined up + VA/DC: I-66 Not Lined Up with US 50

I looked at I-66 as a result of vdeane's post above, and I noticed that I-66 and US 50 are not lined up on their concurrency in VA, at the VA/DC line, or at Exit 57 near Fairfax.

EDIT:  I also just saw that US 50 is not lined up at the VA/WV line either though this may be worked on in conjunction with rickmastfan67's WV recentering project.

Bumping as I found the other following points on I-66 that should most likely be lined up:

1 (I-81), 28 (US 17 BUS (Marshall)), 40 (US 15), 57 (US 50-mentioned above), 64 (I-495)

Mike, it may be best to check all of the interstates on this when you get extra free time.  I looked at the VA NMP list and saw many related to just the interstates.

Further thoughts:

US 50 (DC): I-66 label should IMO be I-66_E.
I-66 (DC): US50 should be US50_E.

I-66 (VA):
Quote
Double half interchanges: Usually use one central point and treat both halves as a single, full interchange. Exceptions: a clear gap of at least 0.5 mi/0.8 km separates the two halves, or each half connects to a different highway that we are also mapping.

How would this rule affect Exit 71?  The eastern half with the WB exit directly connects to VA 120.  The western half does not directly connect to a route.  I would most likely move 71 to the western half, and create 71A to line up with VA 120.  VA 120 already has points at both set of ramps.

US 50 (VA)
1.  The point at VA 286 needs to be lined up with it.
2.  Maybe add a point at SR 645 (Stringfellow Rd) as it directly connects to the I-66 HOV (Future HOT) Lanes.  Maybe SR 657  (Centreville Rd and Walney Rd) as well due to connecting to VA 28 via the Williard Rd and SR 662 (Westfields Blvd) interchanges.
3.  Reed St would be better served at SR 626 (Plains Rd).

I made all the fixes to US 50 in Virginia.  The I-66 in Virginia exit 71 does not meet the criteria to make two interchanges (distances are <0.5 mi).

I did not assess or address the DC items...
