In addition to connecting the local lanes in all the directions, I think it connects eastbound and westbound express lanes to northbound express lanes and southbound express lane to westbound express lane. and a track from a tunnel going westbound and local roads thread their way through the maze of overpasses.
The stack interchange is over 103' (31.4m) high. Before the interchange opened, it was used to make the 1994 Speed movie. It was also used in 2011 and 2015 to make Samsara and La La Land.[wikipedia]

| Interchange ,USAπΊπΈ For Engineering information visit ππhttps://bit.ly/2CK0pBf Lee Stephens: Known as Spaghetti Junction! Where I- 65 I-64 and I- 71 converge in Downtown Louisville, KY USA. I just call it gridlock! Christopher Boden: Why do some sections of road fork off then join the same bit of road again? Kevin Fransen: Christopher Boden are you referring to the freeway going from the top left to the middle rightin the photo? That is Interstate 65. You’ll notice that there are barricades dividing the lanes.Taking the left 2 lanes will keep you on I-65 South. Taking the right lane will allow you to exit onto surface streets. There is an entrance back onto I-65 Southbound though. That is because those lanes are used for Eastbound/Westbound I-64 drivers who want to go South on I-65. |
When I-65 was built, the John F. Kennedy Memorial Bridge was opened in 1963 to carry that Interstate across the Ohio River. The Abraham Lincoln Bridge was added in 2015 to help relieve the congestion. A big part of that 2015 project was building a new interchange on the south side of the bridges. They had to build the new interchange while maintaining traffic flow through the interchange. I had the "thrill" of driving through that intersection during construction. You had to read the signs fast and be prepared for being jammed into another lane. And each time I went through it, the maze was different. Hopefully it now has proper merge lanes so that the traffic is not jammed together. This construction caused tolls to be added to the I-65 bridges.

Here is a "before" image:

Using a road map to get the big picture, we see that I-64 is an east/west highway and I-65 is a north/south highway. I-71 starts at this intersection and goes towards Cincinnati.

How many of these interchanges do they have. Some of them have rather sparse traffic.

I spent more time looking for this. I thought an intersection with five "spokes" would be easy to find. I found a lot of flyovers in Guangzhou, but not this one.

 |
| Highway Engineering Discoveries posted The High Five Interchange is one of the first five-level stack interchanges built in Dallas, Texas. Located at the junction of the Lyndon B. Johnson Freeway (Interstate 635, I-635) and the Central Expressway (US Highway 75, US 75), it replaces an antiquated combination interchange constructed in the 1960s. |

Highway Engineering Discoveries posted [A lot of comments called this a good design. My reaction is that it is a bad design because to make a "left turn," you have to cross three lanes in less than a quarter of a circle. Some comments point out that if you miss your exit you can go around it catch it again. I think it is better to simply have a flyover ramp that makes the left turn without having to look for another exit. This design is better if a lot of people have to make a U-turn, but I don't understand why a lot of U-turns would be needed.] |
