It has just been announced that if coalition talks begin next week between the Greens and SPD, there will be a building freeze for the Hochmoselübergang. (For the duration of the talks which will be 5 weeks.)
This looks very likely to happen!!!
This second article states that no new contracts can be signed and nothing destructive can be continued or begun along the Mosel stretch of the route.
Here’s the official announcement: http://bit.ly/h7MBE8
