Does anyone here (other than me) think it's time to upgrade Nashville's infrastructure considering it's getting crowded and traffic is increasing? And how should it be upgraded? What can be done to upgrade the infrastructure of the Nashville area as a whole to handle the population increases?

So to keep the protestors at bay. I have moved this to the top

I will add one thing. As badly as Nashville needs the upgrades, Memphis is probably more needy.

No, the folks that moved in knew what the infrastructure was.  They want to come in and not pay additional impact fees, so no we should not pay for upgrades, notwithstanding safety upgrades and maintenance.

i think thats basically everywhere.
the problem is until satellite toll pricing is a thing, counties and states have to learn to increase gas taxes yearly, not every decade or 4. gas taxes have to be raised based on the demands of the state, which can change from year to year. still tho, i think its because people enjoy lower gas taxes so they think its okay to complain to the locals. states and counties have to organize a way to increase yearly without pissing off the majority.

Does the sign in the background here at the Nashville Int'l Airport have an error US 255 shield?

Yes. I've seen close-ups of it.

There's 2-3 of them as you leave the parking/rental car garage of Nashville International Airport.

Quote from: I-39 on April 09, 2022, 11:11:42 AMThe Bucker/June Lake Blvd interchange in Spring Hill is scheduled to be ready by April 2023. Pretty aggressive timeline if you ask me, but good to see this critically needed project moving forward with urgency. Buckner Lane won't be finished by then though.

This interchange was opened finally at the end of May of this year (2024). I did a drive-through of it back on June 2nd:

With this opening, the urgency to widen that short section of I-65 between I-840 and SR 396 is ever more apparent.

Have they started to widen any portion of US 31 from Franklin through Thompson's Station to Spring Hill yet?  A US 31 widening could potentially provide some degree of relief to I-65.

No, and (ridiculously), they don't plan to start the widening there until the early 2030s.

With the June Lake and Spring Hill Commerce Center developments going in, in addition to the rapid growth of both Spring Hill and Columbia (most traffic uses I-65>SR 396>US 31 to get to Columbia), that section needs to be widened ASAP. Widening 31, while needs to be done, won't help much with I-65 traffic.

I think the biggest problem with Nashville is that three major Interstates (24, 40 and 65) have downtown chokepoints and long concurrent routings, which forces long-distance traffic in with commuter traffic. There is also significant weaving as routes keep moving around.

Short of a completed I-840 beltway on the north side, a few ways that could be solved could be by moving the routes around (again) to try to give each corridor its own routing as much as possible. How I'd route the Interstates around Nashville:

* I-24 would be moved to the Briley Parkway, bypassing downtown. That would require upgrading the southeast section and the systems interchanges.

* I-40 would be moved to I-440 (that designation ceases to exist), also bypassing downtown. Ramp improvements would be required in the Spaghetti Junction area to ensuring that 4 lanes in each direction remain on I-40 through the interchange, without merging onto I-324 (was I-24).

* I-65 would maintain its current routing, but would no longer be concurrent with any other route.

* The freeways that 24 and 40 are removed from would become 3di's as follows:
** Current I-24 and I-40 on the south and east sides of the Inner Loop would become I-265 (it comes back, but on the other side).
** The stubs of I-24 inside of the Briley Parkway become I-124 in the north and I-324 in the south (with I-324 also incorporating the I-24/40 section southeast of downtown) although those could be unsigned to minimize confusion (sign as TO 24, TO 40 and TO 65).
** I-40 between I-65 and I-440 (renumbered to I-40) becomes I-740.

A big issue here would be the upgrade of the Briley Parkway between I-40 and current I-24.  That would be costly with the space that is needed.  You also need to have through ramps built to connect both as run through I-24, and you also will need to do the same with I-40 in its transition to I-440 and off. 

I'm still hopeful of an extension of I-840 (or whatever they want to name it) up to Clarksville and I-24, and perhaps an upgrade of the TN-109 corridor to complete interstate type expressway from Portland down to I-40 (that probably is a bit more likely).  They could probably leave the connection between I-65 and I-24 near Springfield for another century.

RoadMaster09

Agreed that the Briley Parkway's southeast section would need significant work and buyouts to bring it back to I-24 (the southwest part of the loop doesn't need to be upgraded though, as it is close to I-440).

That's about the only way I could figure out to keep all the routes separate.

It would have to be I-524, because I-124 still exists (although unsigned) in Chattanooga.

The Ghostbuster

I doubt any major upgrades will come to the TN 155 Briley Parkway beltway, let alone upgrades to Interstate Standards. So, Interstates 24/40/65 will likely remain on their existing alignments. The most I can see changing at the Interstate junctions is to move all left-handed ramps to the right-hand side.
