US 101: mileage is measured from a south end at the bridge that carries I-10 west over US 101. If we're not going to start the file there, we should probably do it where the freeways actually merge near Lorena Street. Then we get the following interchanges:
I-5
http://www.openstreetmap.org/?lat=34.025406&lon=-118.205638 (note: I-5 needs a point here)
EucAve
http://www.openstreetmap.org/?lat=34.026977&lon=-118.209661CA60
http://www.openstreetmap.org/?lat=34.029474&lon=-118.215294SotoSt
http://www.openstreetmap.org/?lat=34.030818&lon=-118.2178981A
http://www.openstreetmap.org/?lat=34.034066&lon=-118.221227 (note: shouldn't line up with any other freeways)
In any case, there is no access between US 101 and I-10, so we shouldn't have a waypoint that includes I-10.
Then 1A -> 1B, 1B -> 1C. The separate northbound 1C (not currently included) is arguably part of 1E.
US 101: 2A needs to move south to the centerline, and probably east to the underpass

US 101: GeaSt -> GeaBlvd?
