A14, motorway maintenance project Buchrain-Rütihof

At the beginning of April 2022, construction work will start on the N14 motorway section between the Gisikon and Rütihof junctions. The task includes maintenance of the drainage system as well as pavement replacement and renewal of the guard rails and animal fences over the entire section.

The traffic installations required for the maintenance work will also be used to enable renewal of the expansion joints on the 420 m long Reuss bridge. R+R is contracted by the Federal Roads Office as client’s support staff and external site management unit.

Oslo T-bane CBTC-Project

After two tendering rounds with, at first, four tenderers, Sporveien, the operator of Oslo City’s public transport system, awarded the contract for equipping the metro with a CBTC system to Siemens. R+R has edited the price formats, evaluated the commercial tenders, and supported the negotiations. At the same time, in the Datalink sub-project, Sporveien procures the communication services and the necessary upgrading of the communication infrastructure.

A1, Extension of the Zurich Northern Bypass

Twenty years ago, a serious fire disaster occurred in the Gotthard motorway tunnel. To commemorate this event, the «SRF Aktuell» TV program has produced a report on road tunnel safety in Switzerland, which was broadcast on October 21, 2021. Many lessons have been learned from this disaster. By using the third tube of the Gubrist tunnel, now under construction, as an example, the FEDRO project managers explain recent developments concerning the safety of road tunnels.

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.

A1 EXPANSION NORTHERN ZURICH BYPASS

The northern Zurich bypass between the Limmattal interchange and the Zurich North junction became operational in 1985. Today, the traffic volume at this motorway section exceeds 120’000 vehicles every working day. Traffic jams are frequent and there has been an increase in the occurrence of accidents.

The Federal Roads Office is improving the traffic situation on the northern Zurich bypass with an extension of the roadway to six lanes and the construction of a third tunnel tube.

Other core aspects of the improvements included in this key federal project are the two redesigned junctions at Weiningen and Zurich-Affoltern, as well as a new 100 m long covering in Weiningen. As an environmental compensation measure, a 580 m long covering with recreational areas will be constructed between Katzenseestrasse and Horensteinstrasse. The two existing tubes of the Gubrist tunnel will also be refurbished. Extensive environmental protection measures are to be implemented for the entire project and in particular for the protected marshlands around the Katzensee. The improvement also requires flanking measures in respect of traffic to provide effective and sustainable support for a transfer of traffic from other main roads to the high capacity road.

With few exceptions, two lanes in both directions will be continuously available for traffic for the entire duration of the construction phase. The excavation material of the third tube of the Gubrist tunnel will be loaded onto railway wagons via the temporary loading station in Zürich-Affoltern, and deposited in the quarry Oberegg, AG. Thanks to this measure, roughly 100‘000 truck trips will be avoided.

R+R has advised and assisted the Federal Roads Office ASTRA since 2008 as staff unit for the overall project owner in project management and since 2011 also as staff unit environmental consulting. As project-owner support, R+R is responsible for contract controlling, cost and budget management and the implementation of environmental protection measures.
