I-69 in TN

Google Maps Street View has been updated to include the section of TN 690/future Interstate 69 from US 51 (northern junction) westward to the TN 21 interchange. It was taken in April, and the Google Car only utilized the southbound lanes. Hopefully, the entire bypass in both directions will be traveled by a Google Car eventually.

Most of the NB and SB lanes are in Street View now, June 2024 date of capture. Still missing a few ramp movements and  southbound lanes between TN 21 and Brevard Road.

Here's another drive video of TN 690 (future I-69) in Obion County. Nice quality.

. Plus straight through US 51/45W at the north end is closed as traffic detoured via the new TN 690 to TN 21 with erroneous TN 22 detour signs.

Plus all asphalt freeway, but concrete ramps.

Not to mention no exit numbers either. It's not that hard to figure out what I-69's future mileage will be. I don't see why not add them. Kentucky is now one step closer to getting their par done as the Wingo reconfiguration is fully signed as I-69. I believe next to the Ohio River Bridge the curves at Fulton are the next drawback.

That configuration is SOP for TDOT.  Only the oldest freeways in the state seem to have asphalt ramps, and only because the concrete has been paved over.  Full concrete freeways are extremely rare in Tennessee.  The only significant ones I can think of right off hand are I-65 on the north side of Nashville, a couple of miles of I-40 in Memphis just east of TN 300/unposted I-69, and I-75 in the Chattanooga area north of I-24.

That makes no sense, as reinforced concrete typically holds up a lot better to heavy traffic loads compared to asphalt. We see that a lot out in New Mexico as well--the freeway mainlines being mostly asphalt, with ramps in some places being concrete.
2-d Interstates traveled:  4, 5, 8, 10, 15, 20, 24, 25, 27, 29, 35, 39, 40, 41, 43, 45, 49, 55, 57, 64, 65, 66, 69, 70, 71, 72, 74, 75, 76(E), 77, 78, 81, 83, 84(W), 85, 87(N), 89, 90, 91, 93, 94, 95

2-d Interstates Clinched:  12, 22, 30, 37, 44, 59, 80, 84(E), 86(E), 238, H1, H2, H3, H201

Prior to being repaved, I believe I-440 in Nashville was almost entirely concrete from end to end.

I also collect traffic lights, road signs, fans, and railroad crossing equipment.

Tennessee feels like it's cheaper to pave with asphalt and do more resurfacings than paving with concrete and going longer before the first patch job/overlay.

Or their concrete lobby isn't as strong in Tennessee.  :sombrero:
"That's just like... your opinion, man."

Alabama's the same way, there's barely any concrete highways left here (with a significant chunk of a surviving section of concrete on I-65 having recently been repaved with asphalt).

Being from a state with more freeze/thaw cycles, I wonder if the increase in lifespan of asphalt pavement in southern states is larger than the increase in lifespan of concrete pavements. It would seem to make sense as states like Indiana are gravitating towards concrete for more projects (I-65 widening, I-465 clear path, I-465 portion of Finish Line) while southern states remain on asphalt.

NY's a mixed bag, with NYSTA being more amenable to concrete paving than NYSDOT...and NYSTA regretting their decisions when the tell-tale "ka-chunk, ka-chunk" starts popping up (e.g., the six-lane section near Rochester; the section between 23-24 is still okay, though).

IDOT and Chicago experimented with a concept of a concrete base with an asphalt layer with the idea the asphalt could be replaced periodically without having to reconstitute the base. It worked for the most part except at the joints. The concrete was designed with a rise to support the joints between segments and they started to fracture and break down after so many years. So when it was time to scrape and pave again, the joints had to be reset/recast in many places.

After the concrete base reached its time limit, IDOT removed the concept and did not repeat it. It poured just concrete to replace it.

Concrete and asphalt technology have come a long way since WW2 and the applications are much different depending on the environment and budgets involved.

A lot of mill and overlay projects over a concrete base are starting to use paving fabrics that functionally add 1.5" without raising the profile. These fabrics are able to help slow the development of reflective cracking at joints

A crack and seat (which makes the concrete behave like asphalt) also works.
