The proposed Rosengarten tunnel in Zurich did not go well with the voters. As a matter of fact it has been flatly rejected.

The proposal was building a 2.3 kilometer long tunnel to solve the traffic congestion problem in the busy street of Rosengartenstrasse in Zurich and also building a tram line on the vacated ground.

The majority of the voters, as a matter of fact as high as 62.8% of them, said 'No' to the project. Many thought the cost was too high to calm down a busy street of only 700 meters: The project would cost 1.1 billion francs. Also many others thought not only it would not solve the problem, but even worse would attract more car traffic to the city.

The project has put the Red-Green city government with their voting base. While the city government presented the proposal, their voting base has been critical. The city government was quick to throw the ball to the No-voters.  Speaking to a journal,  the economics director of the canton of Zurich, Carmen Walker Späh (FDP), said that it was now the turn of the opponents of the tunnel to show how the traffic problem on Rosengartenstrasse could be solved. Next to the failed road tunnel proposal, there have been other proposals like imposing a low speed, building a tram line etc.
