Hello, the indicated intersection is best handled by joining. In version 0.32.0 and earlier, the joining algorithm fails at this intersection due to the presence of extra bicycle lanes and footpaths. If you upgrade to the latest development version, this intersection will be imported as a single junction when using --junctions.join.
