Si, definitely not supposed to be concurrent as the site shows at this time. The city Utrecht could be removed from A2 though, now that it is one section.
Now for me to understand what route goes where to update travels. A2 & E25 are definitely in the lower tunnel. The upper tunnel is confusing though is it N2, or an alternate A2 & E25. Then the surface street is either N2 or just a city street depending on what the upper tunnel is. I guess I will have to wait for more of the project to complete to get the clarity to know the right answer about N2 updates.
