St. Luzibrücke (Chur)
The St. Luzibrücke is part of a planned transport project for the Chur region . The bridge is to span the river Plessur over a length of 465 meters and thus connect the Graubünden Rhine valley and the Lenzerheide area with the Schanfigg and the Arosa holiday region while bypassing the city center of Chur .
History of planning
The Graubünden cantonal civil engineering department drew up a first preliminary project as early as 1970, but it was not implemented for financial reasons. The project approved by the cantonal nature and homeland conservation commission envisaged a bold 575 meter long construction that crossed the Plessur at a height of 150 meters. Six slim supports were supposed to support the 7 meter wide roadway. The estimated construction costs in 1970 were between 12 and 15 million francs.
According to the current, revised planning status, the St. Luzibrücke should begin at the Araschgerrank and lead to the opposite side below Maladers , where it will flow into Schanfiggerstrasse . With a roadway width of 7 meters, it should rise 135 meters above the valley floor at the deepest point.
The financing of the estimated 58 million Swiss francs has not yet been clarified. Federal grants are not secured and are delaying the project for an indefinite period of time, which, given the defensive position of the canton, has caused some displeasure in certain Chur and Schanfigger circles (as of 2012).
During the consultation process, transport organizations such as the VCS warned that the St. Luzibrücke should be integrated into an overall concept that also included public transport.
The alternative to building the high bridge would be the renovation of Schanfiggerstrasse above the Chur Theological University , which, however, would have to be carried out in geologically difficult terrain and would therefore be significantly more costly than the bridge project and would not be able to solve the traffic problems in downtown Chur at the Obertor in a sustainable manner.
The layout of the Schanfiggerstrasse as part of the new Chur – Arosa line had to be checked again. In February 2014, the Federal Court upheld a complaint from six residents. The bridge would have led over their property. The federal judges came to the conclusion that the residents would be affected by shadows cast and there was a risk of objects falling. The Graubünden government therefore had to examine whether variants with a high bridge running further up the valley southeast over uninhabited areas would have fewer disadvantages for the residents. Due to this result, it was initially uncertain whether the St. Luzibrücke could be included as an implementation project in the next cantonal road construction program 2017–2020.
In the run-up to the June 2015 session of the Grisons Grand Council in Arosa, the Mayor of Chur, Urs Marti, expressed a fundamentally positive opinion about the realization of the St. Luci Bridge. It is unclear whether the canton of Graubünden can afford the building without federal funds, but a better development of Arosa and the associated relief for the city of Chur could result in a double benefit, which allows a closer look at the financing.
On September 8, 2015 it was announced that the Graubünden government is ready to include the project in the road construction program 2017-2020 and to plan the necessary financial resources for further project work. It corresponds to a parliamentary mandate from the Chur Councilor Ernst Casty . In the absence of direct federal contributions, however, the government assumes that the general Graubünden road bill will continue to be funded by the federal government and canton in the framework of previous years. Against this background, the Graubünden Civil Engineering Office is pushing ahead with the amendment to the comparison of variants required by the Federal Supreme Court. Subsequently, a project approval procedure capable of objecting to the extended study must be carried out, which is why it is not yet possible to set specific dates with regard to the existence of a project that is ready for construction.
At the end of August 2016, Government Councilor Mario Cavigelli confirmed that the CHF 60 million project had been included in the canton of Graubünden's road construction program from 2017 to 2020. A start of construction before 2020 still seemed possible at the time.
After an in-depth examination of the variants, the Graubünden government decided on September 15, 2017 to cancel the project for the St. Luzibrücke cross-connection from 2008 and to commission the civil engineering office to develop a new project. The bridge should no longer run in a wide "S" over an inhabited area. Instead, it should be more straightforward, but 120 meters longer and also a little steeper. The estimated costs of 66 million francs exceed the previous project by around 11 million francs. Construction is not expected to start before 2022, and not to be completed before 2027/28.
