Texas frontage roads often feature inverted diamond interchanges. Instead of having an auxiliary between two cross-streets, they have it the other way around, with the auxiliary lane located on top of the viaduct across the cross-street.

So when you approach the cross-street on the freeway, traffic merges from the previous cross-street, as opposed to Europe, where traffic leaves the motorway at that point. So traffic on Texas freeways have to exit earlier than in Europe.

I had to correct it, because I forgot about the Grot-Rowecki Bridge, which was really first 2x4 section. Now (since 2015) it has 10 lanes (3+2+2+3).

The first 8-lanes motorway in Italy, if we include 2+2+2+2 (4x2) configurations, is A14 around Bologna (1967).

In real life, electronic toll collection was first introduced in Bergen, Norway in 1986, and well into the 21th century many countries still struggle to implement it.

This 8-8 section was already completed in 1991. I presume it was done around the same time as the A16 widening and van Brienenoord duplication.

Also I presume it was also the first 2x7 at least, not A4 between De Hoek and Hoofddorp South which was done much later.

You presume correctly. Both, 1991 and 2000 came before 2013.
