Berkeloo has some major problems with the roads, therefore some avenues had to be changed into highways. I really hated that, but it was necessary
I'm talking about the avenue that runs along the airport, it really blends in the quarters right now and it showed that the city grew as it is today (with some strange crossings and solutions along the way). traffic really started to appear when Rechtsdorp became an industrial area aswell.
The solution is not a really nice one, but I wanted to keep the city's base lay out as far as possible so it maintains it's identity.
building the highway, I hit some new situations (railways an roads that do not align perfectly) so after building a nice ground level highway..
I ended with a lame elevated highway, because it gave more opportunities to underpass (I do like how it makes strange curves) the railway now goes underground. the toll booths you see where just a test... they are removed already because they didn't help to make it realistic, where do you find those nowaday's... (eastern europe highways do have them ocasionally... I don't like 'em as the eu paid a lot of those roads...)
the airport looks a lot more realistic with all these roads around it, I do miss the denser built area around it (for some reason offices don't like to be near airports in this game)
Here's an image showing the economically istability Berkeloo suffers, the fact that the funds are rising even as I built the Highway is a good sign!
As for Rechtsdorp... It's a mess, the buildings are turning grey from bad maintenance everywhere. To fix it I started a project which places parks around the city because the desirablity is very low for almost every kind of structure (even low $ residents!). Also I will redevelop the industrial areas (topleft) and build parks in them

Don't know what the next update brings and when I will make it... Maybe this city needs an entire new lay-out. might be interesting (I'll try to stay close to the main setup)
