The crossing Brunnenstrasse / Bernauer Strasse is one of the busier crossings: not only does the Brunnenstrasse meet the Bernauer Strasse — but there is also the U8 underground station Bernauer Strasse as well as the Tram M10 station with the same name. And the Berlin Wall Memorial is right around the corner.
With all the traffic going on you might miss that the crossing has also a rather decent view to the TV Tower to offer.
