We talked greening and eco-boosting cities the other day. For Berlin, taking down the existing inner city highway is unthinkable, just its planned extensions #16 and #17 are hotly debated and likely won't happen as they were planned. Much is in flux on the east end part. Back to how it is, ~65 years after construction started:

Things changed over time while the number of registered cars went from 100k in the late 1950s to 1.2 million in the 1990s: traffic situation, clogging, and even the freshest concrete turns dark brown-black over time. Fun fact, today, there's around 100k cars per day on any given stretch of it. Fact is, the bus service did work and was useful given relying on the urban rail had political complications left and right.
And I remember the autobahn bus service (then renamed to 5 and rerouted to normal roads) going out of service (in 1990 or 1991 sometime). Back in the 1980s we used a bus service on the highway, and there's a book celebrating reporting on how that worked and how the bus stops were retrofitted.
Ah, history.
