MOTORWAY MAINTENANCE PROJECT SCHLIEREN EXIT – EUROPA BRIDGE (GRÜNAU)

The short motorway section between Schlieren exit and Europa bridge is situated exclusively in a heavily urbanised environment. The four to six motorway lanes are complemented by two adjacent two-lane state roads, one on each side of the motorway. The corrective maintenance project for this motorway section and the refurbishment of the noise protection systems aim to take into account both cantonal and municipal design requirements.

The refurbishment and reshaping of the A1 motorway in the Grünau/Altstetten region near the western border of the city of Zürich covers a road section with a length of one and a half kilometres. In addition to noise protection, the reshaping of the road profile (including the installation of transparent noise barriers and the establishment of a median strip with tree rows) will result in a boulevard-like appearance and improve the motorway’s integration into the cityscape, thereby making the project a unique case. After a period of 30 years without any significant refurbishment measures, the renewal of the asphalt pavement, improvements to the drainage system, the construction of a road wastewater treatment plant and updates to the traffic management system are due. In addition to the operations on the motorway, changes to the motorway accesses necessitate adjustments to a number of communal roads and conduits, which requires close coordination with the City of Zürich and the respective municipal authorities.

R+R advises the Federal Roads Office‘s project manager in a staff function and will also provide construction site management. As this project includes road maintenance as well as conceptual improvements to an urban environment, advanced skills in the fields of project coordination and design are required in addition to conventional project management and controlling tasks.
