Widest or Biggest - roads or interchanges

[ChrisZwolle]

Frontage roads don't count in my opinion. They're not part of the freeway and have driveway access.

The frontage road IS part of I-10. Houston labels it as "IH-10" and is always included in lane counts, as are all access roads for 401 and other highways. This as opposed to, for example, the frontage roads of Sam Houston Tollway, which are a completely different entity on its own called the Beltway 8.

Even if you don't want to count frontage lanes, this segment of I-10 is still the world's widest road by many measures. And like I said, it is perfectly valid to count them because they ARE part of Interstate Highway 10. Think of it this way: Both the Katy Freeway and the frontage roads are comprised within IH-10.

That said, you do make a good point. If I'm including frontage lanes I should say that it is the widest highway, not freeway.

[ChrisZwolle]

Frontage have no freeway design standards (traffic lights, driveway access, etc), so I don't think they should count Many rural freeways in Texas have frontage roads as well, but I don't think people will say "that's an 8-lane freeway".

20+ lanes at widest, Grandview Traingle interchange (Kansas City, MO: US71, US50,I-435, I-470)
This has to be one of the biggest for a city this size (metro 2.1 million)

This is the biggest and the most complicated interchange in Bulgaria:


It is situated in the southern part of Veliko Tarnovo and gathers five directions together, as written on the map. A few closer shots in direction Gabrovo -> Varna:

I wonder if there were photos of this thing posted in this thread? If no then does anyone know how it's called and if there are any good photos online?

I think that it's probably called "spaghetti"...

[beto_chaves]

That's indeed a good nickname for it!

Based on location, I'm going to go with 拉面 (lamian, ramen), although I imagine there are some sinicized Italian joints in the area...

Not sure if someone has posted this already but the Downtown Connector (I-75/I-85) in Atlanta carries more than 272,000 vehicles per day and generally has 12-14 lanes including 2 HOV Lanes for each direction of traffic.
