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.

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.

CORRECTIVE MAINTENANCE PROJECT A1 EFFRETIKON – OHRINGEN, TÖSS BRIDGE

The 162 m long Töss Bridge between Winterthur Töss exit and Winterthur Wülflingen exit was renovated between March 2014 and July 2015 under continuous operation. The renovation of the bridge is one of a total of eight preliminary measures that have been separated from the more comprehensive corrective maintenance project Effretikon – Ohringen by the general project management team of the Federal Roads Office and which are being implemented in advance.

The approximately 12 kilometres long motorway section of the A1 between Effretikon and Winterthur Ohringen was built more than 40 years ago and is to be extensively renovated from 2017 until 2021. The refurbishment of the Töss Bridge forms part of this corrective maintenance project of the Federal Roads Office, but had to be tackled in advance due to the poor structural condition of the bridge. Construction work was carried out without reducing the number of available lanes, although the construction site required the reduction of lane widths according to the respective standards and a speed limit of 80 km/h instead of 100 km/h. Maintenance work comprised structural improvements of bridge and abutments, the replacement of expansion joints and bridge bearings, concrete refurbishment as well as the renewal of sealing and pavement.

Throughout all phases of the Töss Bridge renovation, R+R provided support and assistance to the general project management team and was involved in construction site supervision. Tasks notably included monthly project controlling with supervision of costs and work progress. Thanks to favourable weather conditions, considerate planning and work execution in two shift operations, the Töss Bridge could be reopened to traffic nearly a month earlier than planned.
