Mike, I think I understand what you are going for. I know I am partially biased towards my home area (I lived near Hopewell most of my life until a couple months ago) when it comes to routes, but I realize that you do need to be realistic on where people are driving to (whether being local or out-of-town).
I also went through the US 1 file and a couple others to check on direct connections to interstates (and other minor stuff) because I noticed at least one was missing. I will add those to this post when I find the paper I put them on.
EDIT: Points that I found considerable:
US 301-the VA 35 points should be N and S instead of W and E
Note: I am not saying anything specific about US 1 in Petersburg. I am so used to using Adams St the technical routing on Jefferson St only exists on paper to me.
US 1 AND US 301(all of these are on the duplex):
Dupuy Ave: Mainly debatable due to the presence of VSU and it does connect to VA 36 via E River Rd and Granger St in Ettrick. VA 36 does have a point at Granger St.
Ellerslie Ave: I would expect the consensus to lean towards "no" here. Though with the weight limit on VA 144 SB west of I-95, I am somewhat surprised there is not a VA 144 Truck following Ellerslie and Conduit Rd back to VA 144 by Southpark Mall. (I blame the US 30 BUS ALT Truck Route that exists in Downingtown, PA, which partially even uses the US 30 Bypass.)
SR 746(Ruffin Mill Rd): SR 620 has a point already, two here might be unnecessary but worth mentioning since SR 746 is a part of the I-95 interchange there
SR 613(Willis Rd): This was the missing direct connection (I-95 Exit 64) that got me to look a bit more in-depth. This could have been an oversight due to VA 145 being nearby.
Maury St: Direct connection(I-95 Exit 73). Looking at GSV, there are no "TO I-95" shields at this intersection or even at US 360 (Hull St). I guess this would apply more for the non-existent VA 416 (Commerce Rd).
US 11:
(US 460 Business here as well): Depot St serves as a bypass of downtown Christiansburg that connects to VA 8 and I-81 (to the point where traffic to I-81 is directed to use it from Franklin St (US 460 Business EB). I would rather this part of Depot St be VA 111 than the actual VA 111.
VA 280: The point here just needs to be added. It already exists in the VA 280 file that has been created.
It also looks like the route files (US 11, US 17, US 50, US 522, maybe VA 7) in Winchester need to be updated to the latest routings (as of early 2010 as stated on the US 17 entry in the VA Highways Project).
VA 199:
OldYorkRd: Should be moved to either Marquis Pkwy(MarPkwy) or the entrance to Water Country USA, maybe even consider deleting
VA 114:
SR659: Should be changed to reference the Radford Army Ammunition Plant, SR 659 itself is a loop road that connects to VA 114 on both ends farther east called Vicker Switch Rd (as found in the latest VDOT traffic logs)
US 13:
PitRd: Refers to Pittmantown Rd nearby which does not actually intersect US 13, both Arthur Dr and Boonetown Rd are nearby
VA 314:
SprRd>BeaWay: Spring Road has been renamed
Beamer Way after now former Virginia Tech football coach Frank Beamer
Mike, I am trying to understand how the TM system works by looking into this as well. I am not really sure what the mindset exactly was when some of these files were originally created though I believe you made it clearer to me what points should be there and what should not. I also added a few more to this post than you originally saw.
Thanks,
Mark
