Busiest north-south and east-west Interstates in the nation?

[RoadWarrior56]

Strictly based on the truck traffic map above, if I-65 north of Nashville, I-24 between Nashville and Chattanooga, and I-74 south of Chattanooga were a single continous route, it would be the busiest N-S route.  As somebody who drives much of it frequently, IMO, it would be one of the busiest overall.

Typo above - I-75, not I-74.

Froggie did a map of total Traffic. I noticed it like 81, 39 in Illinois doesn't pass through any big metros but it bypasses one and for free(for now, it could be tolled at will by Illinois because it was not an original)
I also noticed it includes all the NHS routes . One of the thicker lines in the Midwest is US 218/IA 27 . I know it carries about 2000 trucks and it is one of the busier non Interstate route

I found this list:
http://listosaur.com/travel/10-busiest-interstates-in-the-us/

However, I believe this list is based on density, not overall traffic since it lists some 3-digit Interstates.  Here is the list:

1. I-95
2. I-405
3. I-5
4. I-90
5. I-15
6. I-110
7. I-45
8. I-10
9. I-80
10. I-85

It looks like this list shows the top ten interstates by the volume occuring on short individual segments only - it doesn't attempt to rank the entire length of the highway.

Froggie did a map of total Traffic.

Can you, Froggie, or someone else provide a link to this map? Thanks.

You just reposted the Z Mapper map on the if the interstate system wasn't built thread. I hope Froggie can remember where he put that map. He did it about a year ago because that was when I was last posting regularly. It was a red flow map   like the truck volume map we have here that he made from the raw data at FHWA. He mentioned doing another for other routes( US or NHS like the Trucks?)
All I can recall is it was a post under General Highway Talk

Is this the one you're thinking of?



This is the one where I thought the lines were all too close to the same thickness.

I posted the original maps on my Flickr page.  Here's the one people are asking for:



It shows just the Interstates.  Of note:  since I created this map, I've learned that the traffic data is 2002 data.  I'm in the process of acquiring more recent data for a map update, though it's taking awhile.

Thank-you Froggie. ! Don't rush . I hope I speak for everyone on this site when I say how Appreciated this is

Most interesting part to me? Look at the I-85 corridor in North Carolina. It looks like we're getting VERY close to a continuous urban strip (at least in terms of traffic) from the Triangle to the Triad and down to Charlotte.

This is a really nice map.  Sure, updated data would be nice, or the differences between them to highlight areas that are growing fastest.  Or the whole National Highway System   But this is really helpful.

Looks like I-75 may be the second-most heavily traveled N/S interstate. According to that graphic, it travels through fewer "dead zones" than I-95 (basically anything between Jacksonville and Richmond).

As for an E/W interstate, looks like I-4 has the highest density, but it's probably not long enough to count for this discussion.
