Thread bump:

Is this flyover strictly necessary?

I remember once upon a time HB said something about coal trucks going down the hill, I'll let HB clear that up.

I think you're getting two separate posts by him confused.  The two locations are actually about 25 miles apart.

This one is close to there in Inez, KY. This is a typical intersection for KY 3 and KY 645 except there is a flyover to stay on KY 3 NB:

I haven't been there since that was built. I never really understood the need for it, but I think it was done to keep traffic staying on KY 3 north from  pulling across four lanes of traffic, so I guess it was justified for safety reasons.

There are also plans to build a grade-separated interchange at KY 3 near Louisa. (Which, in my view, is a total waste of money. The current signalized intersection is at the bottom of a long downhill grade going north and the exit is being built, supposedly, to keep coal trucks from running the red light and slamming into vehicles that have the green on KY 3. I'd solve that by spending a few thousand dollars to put a mandatory truck stop at the top of the hill, instead of millions for an interchange.)

I had the intersection right but the coal truck part wrong. But probably the same thing can be said as there's a downhill leading to the intersection from 3.

Exit 56 for I-78 in Newark (unbuilt freeway, cancelled due to NIMBYs)

Once you get more than 10 or so miles north of Fort Wayne, IN 3 being 4 lanes seems unnecessary.
Similarly, more than a few miles south of Huntington, IN 9 being 4 lanes seems unnecessary.
I'm also amused by IN 520 being 4 lanes.

I-69 will be overbuilt as it is unnecessary.

OH 11 is a full freeway with an AADT with 6k. That may justify a divided 4 lane with at-grade intersections, but I'm questioning why ODOT spent their resources turning this into a full freeway, instead of US 23 between I-270 and US 35 (AADT 20k-30k) and the Columbus-Toledo corridor.

The mainline Texas section up to Tenaha is pretty useful. Houston will have a connection on its northeast after its done, and using I-369 from Tenaha to I-30. The branches south of Victoria are their own issue. I think 69E should be mainline 69, 69C removed and 69W to a 3di, but that's fictional.

There were two issues with the KY 3/KY 645 flyover near Inez. One was coal trucks coming down the hill on westbound 645. The other was slow-moving traffic (again, including coal trucks) making the left furn from northbound 3 to northbound 3/westbound 645. There is a very short concurrency of the two routes before KY 3 northbound makes a right turn off the four-lane to head into downtown Inez on its original routing.


Government would be tolerable if not for politicians and bureaucrats.

Turns out, unbelievably, there is one in Pennsylvania (where very little is overbuilt). A 2.5-mile four-lane divided highway bypassing Milesburg on Alternate US-220 and PA-150. Two lanes on either side, where one is really all that's needed. I imagine that, before I-99 was built, they meant to upgrade existing Route 220 to 2+2?

I-73 in southwestern Greensboro.
8 lane urban freeway, I don't see how it's necessarily overbuilt.

which is really all that's needed.

So it isn't overbuilt?
Good catch, thanks. I meant two lanes total is all that's needed - four is overkill.

I've said this many times on this forum, but I think some state DOT's (specifically Wisconsin) are starting to overbuild freeways.

This is 2nd Concession in East Gwillimbury, Ontario. Why they decided to turn this 2-lane road into a 4-lane road with bike paths is a mystery to me, considering that there is absolutely nothing there, and it is also not a heavily-travelled arterial either.

I-73 in Greensboro used to be that way, but I do believe it can still support only 6 lanes instead of 8. Just my consideration.

Can't think of anything else...

If this is in reference to the 8-lane stretch between I-85 and I-40, originally I-40 was also signed over that section with I-73, so the facility, part of the Greensboro Bypass loop, was built to accommodate the peak traffic for the combined routes.  Later it was decided to revert I-40 to its original routing, so I-73 now occupies the 8 lanes by itself.  It could be restriped for only 6 lanes, but there's no compelling reason for doing so unless NCDOT elects to do that to keep traffic wear & tear off part of the carriageways.

MO 364. In some areas, there are 5 lanes in each direction when 3-4 is enough.

I don't think it should or needs to be narrowed down. It's fine the way it is.

I have to disagree somewhat.  When bridges on I-70 and I-64 were being rebuilt, those extra lanes made a huge difference.  I think they'll need to widen MO 364 from Mid Rivers to I-64 fairly soon. The population growth is quite rapid in western St. Charles County.
