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.

A1 OHRINGEN – OBERWINTERTHUR MEASURES TO OPTIMIZE TRAFFIC FLOW

During peak hours, the motorway section between Winterthur Ohringen and Oberwinterthur is highly congested. To ensure a stable flow of traffic, as well as to minimise potential backlog at the junctions, measures are being taken by the Federal Roads Office to improve and optimise the traffic situation. In addition, constructional adjustments are being made and traffic signal systems are being installed at the junctions.

Section 48 on the national motorway A1 between Winterthur Ohringen and Oberwinterthur ranks among the most congested motorway sections in Switzerland. Stretching 4.3 kilometers, it is jammed during peak hours on a nearly-daily basis. This bears negative consequences for the road networks of the Winterthur city agglomeration. The implementation of measures to optimise traffic flow is due to alleviate congestion during peak hours on both the motorway and secondary road networks, as well as to minimise the risk of accidents. Amongst other things, these measures include extensions of the Oberwinterthur motorway junction and the acceleration lane at Forrenberg service station, the widening of existing emergency bays and the installation of a total of 19 signalling portals. The total costs of the project amount to 29 million Swiss francs. In order to prevent traffic backlog at the junctions, constructional adjustments are undertaken and new traffic signal systems are being installed at the junctions Winterthur Ohringen and Oberwinterthur.

The scheduled measures serve as an interim solution until the 6-lane extension between Winterthur Töss and the intersection Winterthur Ost will be commissioned. Current plans call for the motorway extension to be implemented between 2035 and 2040. Holding mandates as project-owner support unit and construction supervisor, R+R has been providing assistance to the general project management team of the Federal Roads Office since early project stages. In this capacity, R+R supports and advises the general project management team in project management, project controlling and in other selected issues.
