Pro Natura has withdrawn its objection now that the required replacement measures have been defined. The organization has an interest in a certain amount of canalization for mountain bikers and is now sympathetic to the project, says Hans Fritschi, Vice President of Pro Natura Berner Oberland, in an interview with the Berner Oberländer newspaper. However, another objection is still pending, and the initiators are now also hoping that it will be withdrawn.

If all goes well, construction could begin in late summer this year and the route could then be opened in spring 2016, explains the media spokeswoman for Jungfrau Railways, which supports the project as a member of the Grütschalp Bike Route Association. The corresponding building permit was requested almost exactly a year ago and it is now hoped that things will progress quickly.Further information can be found in the news report from the Berner Oberländer:
