There are often accidents in this area.
They plan that from the Wilson/Smith County line all the way to Monterey, with trucks only allowed in the right two lanes. They did one Smith County portion last year, and it's definitely needed very badly. I'm especially in favor of widening the Cookeville/Monterey and Buffalo Valley/Silver Point grades

Really??? Interesting, I would have never thought of that.

I don't think this is true... I found one source putting TN at 3rd with 1,959.54 mi (link), but every legit government source I could find has much lower values for the state.

https://www.fhwa.dot.gov/highwayhistory/data/page07.cfm - Lists the top 5, and TN isn't on it
https://www.tn.gov/tdot/100years-hom...nterstate.html - Has TN with 1,105

A quick check:
I-40: 455 mi
I-24: 185 mi
I-75: 162 mi
I-65: 122 mi
There's also I-81 and plus a few loops and spurs, but nothing even close to 1,900 miles.

So 1100 for TN, and a little over 900 for KY.

What makes KY different is the miles of parkway built back when that were built as toll roads. When the bonds were paid off, the parkways are now free. AFAIK they are named & not numbered. They may not fit modern interstate standards with interchanges, medians & other factors. The new I-69 follows the route of a Parkway from Hendersonville west to near Paducah and on to Fulton. I-169 connects with I-24 near Ft Campbell. Someday there will be a new bridge over the Ohio to Evansville IN.

In TN we have more 4 lane highways connecting the county seat to the Interstate. Someday soon TN needs to build I-69 from Fulton KY to Memphis.

You're right.

In fact, they have plans to connect EVERY county seat one day. 2/3 of the way done for Celina and already surveying right-of-way to finish up Wartburg.

I wonder what route they'll follow when they do Gainesboro. SR 56, whether with or without 290, would seem the most sensible, but I'm hoping they do SR 53 and 264 instead; it's actually slightly faster to get to Nashville, which anchors Middle Tennessee's economy into place (with Murfreesboro and Clarksville as other primary hubs).

But I'll make a separate thread about that. I don't want to get this one too off-topic.

When I leave Crossville I take 127 down the valley to US-111 to US-27 south I-24 to I-75 to FL.. It's shorter and faster than going east to get on I-75. I think it is possible to widen I-75 across TN but not practical unless it is made a toll road to pay for accelerated completion. I-75 in GA and FL is an ongoing thing. Constructing super highways in landslide country is not an easy feat. I've seen boulders in the roadways at times that would crush a semi. Repair is ongoing on I-40 now where the mountain side seems to be slipping downward. All can be done with enough dollars in the pot.
