While the road's extension to Oberursel-Nord was easy to build, the construction to Frankfurt-Eckenheim got significantly delayed.

The section between Offenbach and Egelsbach was also already constructed, but at this time as a part of the A 49 which was planned as an Autobahn between Kassel and Darmstadt.

At the newest section between the Friedberger Landstraße and Frankfurt-Ost (close to the Eissporthalle the lanes are very tight because of economy measures.

There is no hard shoulder at the moment and the lanes are only separated by a one meter high concrete wall.

The expansion joints were not large enough to fit the concrete slabs when they expanded because of the heat, the police said.
