A1, Extension of the Zurich Northern Bypass
The main construction work for the Weiningen motorway exit and the covered road section will start on August 16, 2021. The Weiningen exit will be relocated and moved around 200m closer to the Limmattalerkreuz junction. In addition, all three Gubrist tunnel tubes will be extended by a new 100m covered motorway section. This will reduce the noise and pollution levels of the adjacent residential areas. From mid-August, the top pavement layer of the roadway in the new third Gubrist tunnel tube will be installed over a period of approximately 3 weeks. Thus, most of the construction work will have been completed. In autumn 2021, installation of the traffic control and safety systems for the third Gubrist tunnel tube will start.
R+R has moved
Since June 1, 2021, the R+R offices have been moved into new premises on the 6th floor of the Duplex building in Baden at Brown Boveri Strasse 12. As before, we are still at a very central location within the city of Baden. As you notice, we also took the opportunity to update our website. We hope you enjoy the new content, and we look forward to welcoming you in our new offices at the next opportunity.
Oslo T-bane: CBTC project reaches important milestone
Oslo has an extensive metro network, the oldest in Scandinavia. Five lines serve 101 stations, and, in the central section, trains run every minute. Today, three different interlocking technologies are in use, some of which are already quite old. Over the next few years, operations will be converted to the communication-based train control system CBTC. At the beginning of February, four suppliers submitted initial offers for the system’s introduction and operation in the following twenty-five years. R+R supports the customer Sporveien with the evaluation of offers and the upcoming negotiations.
ETCS introduction in Finland
As part of the Europe-wide introduction of the interoperable train control system ETCS, Finland is examining the right strategy for the country. Fintraffic Rail develops pioneering digital solutions under the “Digirail” label. By the beginning of 2020, a wide range of variants had been presented, for which R + R provided rough estimates of the life cycle costs. In the meantime, Fintraffic Rail has derived an ideal solution and has examined it in depth. At the beginning of 2021, R + R developed a refined cost estimate and compared it with the costs of a fallback solution. In addition, R + R supports the assessment of cost uncertainty and the cost consequences of risks.

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.
