Inner Ring Road, Berlin

In the southern part the route is identical with the historic customs city wall that was begirding the Old Berlin until 1861.

In the western part there had been the Entlastungsstraße road cut through the Great Tiergarten park to avoid the places around the Brandenburg Gate and the Reichstag by about a mile.

In the northern part the route takes advantage of one of the Hobrecht-Plan ring roads which runs considerably more outside of the Old Berlin limits so that there is no historic connection from Invalidenstraße to Bernauer Straße.

The open space at Bernauer Straße is a consequence of the Berlin Wall which led to old buildings along the street to be torn down.

[1] The senator announced that construction will start in spring of 2011 but one can not expect the new road to open before the mid of 2013.
