TDOT is currently in the planning stages of cleaning up the mess that is the Ellington Parkway / Spring Street / whatever other roadways interchange on I-24 in the inner loop. This is fine on its own but it really needs to be coupled with a project to widen Ellington Parkway and fix deficiencies in its interchange ramps, followed by designating Ellington Parkway and portions of the inner loop as I-465 (or whatever I-65 loop number).

I didn’t think I was going crazy when I thought I heard that was in the works. I may be about half way to crazy but not there yet. 

As far as the inner loop that horse has been beaten and eaten by vultures and hopefully TDOT and the State will figure out a way to fix it. Hopefully it’s not what they did in Austin with levels below and above and what they have planned because there is not room for a 20 lane wide interstate here like the planned I 35 thru Austin..I can see an elevated  double decker loop and I think our friend Diane Black proposed that. All I can say is Oh the humanity, as  It will probably be a  cluster not to mention a ten year construction project no matter what they do when they fix the inner loop.

I have been preaching for those changes to Briley for years.

Just to be clear, the I-65 widening is not really geared towards lessening commuter congestion. I think I said on here before that the truck percentages on this stretch are as high as 40%. It's true there are other options for moving these goods but I-65 is a fairly critical freight corridor for the continent and supply chains aren't getting any less fragile.

As a percentage of total traffic there aren't really enough commuters from Portland, White House, etc. for this project to move the needle much on congestion. That being said, the slowdowns at Long Hollow Pike should go away once all segments of the project are completed because it will remove the lane drop at that exit. Vietnam Veterans Parkway is going to continue to be an issue just because of the volume of commuter traffic entering/exiting I-65 there.

TDOT is currently in the planning stages of cleaning up the mess that is the Ellington Parkway / Spring Street / whatever other roadways interchange on I-24 in the inner loop. This is fine on its own but it really needs to be coupled with a project to widen Ellington Parkway and fix deficiencies in its interchange ramps, followed by designating Ellington Parkway and portions of the inner loop as I-465 (or whatever I-65 loop number). This would better utilize the roadway in off-peak hours and get some traffic off the I-24/I-65 concurrence near Trinity Lane.

The second item would be converting Briley Parkway between I-24 and I-40 (near the airport) to fully controlled access and making all of Briley Parkway I-224 (or whatever I-24 loop number). This provides a bypass for I-24 traffic through Nashville and also picks up the not-insignificant traffic between I-65 north of town and I-24 east of town, as well as taking some pressure off the inner loop. But all Briley interchanges not on I-40 would need fairly substantial reconstruction.

The inner loop itself needs a lot of work but that horse has been beaten to death.

This also isn't technically an Interstate project but the Portland bypass will help divert some traffic onto SR 109 (which provides a fairly high-speed link from the TN/KY border to I-840 in Wilson County). But it faces the same issue as the projects listed above. You really need controlled access and Interstate shields to get national traffic diverted off a roadway. If it were up to me I would have at least run I-840 up to Gallatin and connected it to SR 386, making the whole thing controlled access.

It would be really nice if there were a comparable project to SR 109 from I-840's western terminus north to Clarksville, say along SR 48 and SR 13. I'm not sure how the connection to I-24 in Clarksville would work; there was supposed to be an extension of SR 374 across the river at one point.

This is all super helpful, thank you! I think the widening will accelerate the development that’s already started up on the plateau in White House, likely to continue moving out towards Portland (anecdotally, my wife has worked in Portland for several years and sees more families commuting to jobs in the city).

I agree that modernizing ramps on Briley should be a priority to make it interstate-ready, but I don’t love the idea of Ellington as an interstate. Did I dream that there was a TDOT plan to take Ellington to 3 lanes each way in their 5 year plan?

The only project I know of was to add managed/transit lanes to it, presumably for BRT. That shows up in the GNRC long-range plan and the TDOT I-65 corridor study with a 2030 horizon.

I get that Ellington Parkway is not ideal as an Interstate but it's the quick and dirty way to utilize infrastructure that mostly already exists. It carries about half of the traffic of I-65 north of I-24 and maybe a third of the truck traffic (using TDOT's probably generous truck percentages). It's never going to be equal to I-65 even as a loop of it but especially in the off-peak hours there's pavement there that's not being fully utilized.

I was there with a buddy this past weekend.  He saw the traffic and the crowds and the first thing he asked was if Nashville had a mass transit or subway system.   You already know the answer to which he responded, it needs one and then offered that it's probably too late.  All I could do was shake my head.

Big write-up in today's Washington Post about the impact the infrastructure bill will have on improving and expanding rail transportation in the US. In the article, Nashville is specifically called out as a candidate for expanded rail service.

Is it now on Lee to approve it? I know he has agreed that Nashville / Middle Tennessee needs mass transit to remain competitive. Amtrak could be a great start!

I'm not sure, I don't want to start anything political but the GOP has had an anti-train and anti mass transit mindset for a long time now.  They suggested privatizing Amtrak a few years ago and the feeling I get is that they don't want the government in charge of something that certain politicians will think of as socialism.  I wouldn't even bring up such a thing but there's clearly a stark difference between the political parties on this issue.

What federal infrastructure funds could mean for Nashville bus system, sidewalks, and streets:

The nationwide investment in infrastructure would deliver about $7 billion to Tennessee, according to a state analysis. The bill spans highway and pedestrian safety programs, roads and bridges, electric vehicle charging stations, increased cybersecurity and climate change protections.

Infrastructure bill funds could provide some of the funding needed to implement parts of Metro's Infrastructure Plan, which the Metro Council approved in December 2020.

The proposal to overhaul Nashville's bus system, extend its sidewalks, repair streets and install modern technology came with a contentious $1.6 billion price tag. Before its passage, council members noted the proposal lacked financial backing and a clear timeline.

"contentious $1.6 billion price tag"?  I can't get past paywall. 

What would Mayor Barry's transit plan 5 years ago have cost?  Meanwhile very little has been done, and the cost will continue to rise.  Does anyone else get the sense that Metro Council is actually more of an obstacle to getting mass transit in Nashville?  Just like my point about parks above, it seems that Metro just gets mired in conducting studies ad nauseum.

I love trains and would love to see Amtrak in Nashville, but call me skeptical.    Endless red tape, bureaucracy, and millions and millions of dollars spent on study after study after study.    And don't forget all the well meaning people out there who scream "we don't want Nashville to become Atlanta" simply because that's what they've heard people say so they say it too.

Getting Amtrak to Atlanta will help as we have to start somewhere. 

From all indications it will go to Louisville and Indy first, then on to Chicago before they ever have service to Atlanta. If I were to make my first train journey since I were two years old then it would be to Chicago and not Atlanta. I will not get into it much, but if you are younger Atlanta might be your choice, but not for me anymore. Chicago has a lot more to offer IMO! Besides if you get to Atlanta by train how are you going to get round the city. MARTA pretty much stinks! A north /south - east/ west line that still does not get you where you need to go.
