Never looked that closely at US 70 and NC 50, but this is right in my back yard.
- On US 70, I agree with #1 and #2. TW Alexander is a BIG commuter route. Hop off of 540 and take Alexander over to the Durham Freeway (NC 147) or vice versa. I can verify it has a lot of traffic. It will probably be an interchange in a few years as the NCDOT is talking about converting US 70 in this area to freeway.
- Heading up 70 towards Durham, the point labeled GeerSt is actually Cheek Rd at that interchange. Geer Street runs under US 70 between there and I-85.
- If you want another point on US 70 in Raleigh between I-440 and I-540, Lynn Rd or Millbrook Rd / Duraleigh Rd would be major cross streets to choose from. That's a long run between NC50_N and UmsSP.
- And very good points on US 70 / NC 50 through Garner about Timber Drive and Ten-Ten Rd which are both major city/county roads.
