In 2017/2018, the Federal Roads Office (“ASTRA”) comprehensively renewed the Rheineck to St. Margrethen section of the A1 motorway. The main works will be completed ahead of schedule and significantly below budget. In addition to the renewal of the highway, important sub-projects included the renovation and extension of the noise reduction structures, the construction of the new border control bridge between St. Margrethen and Höchst, the updgrade of the two motorway junctions Rheineck and St. Margrethen, the lowering of the cantonal road in the Rheineck junction, the extension of the motorway service area exits and the installation of extensive storm-water systems to guard against flooding.
C-Matrix supported ASTRA in all areas of project communication: From the organisation of official information and inauguration ceremonies to the answering enquiries from the public and the preparation of media releases, residents’ information and fact sheets.
