A1 expansion northern Zurich bypass

The commissioning of the third tube of the Gubrist tunnel has been postponed until spring 2023 due to the current global economic situation (Covid).

During the night of April 22/23, 2023, there will be a "silent opening" of the third tube to regular traffic. A public festival and the authorities’ event are expected to take place in mid-April 2023.

In early May 2023, the renovation work of the existing second Gubrist tube will start. Westbound traffic (direction Bern) will be accomodated on two lanes in the new third tube, while eastbound traffic (direction St. Gallen) will occupy two lanes in the first tube.

Maintenance project Hagnau – Augst

The GS-DETEC (General secretary of the Federal Department of the Environment, Transport, Energy and Communication) has approved the "Operations Center South East" project. No complaints were received against this decision. Thus, details concerning the construction process of the new operations center next to the east portal of the Schweizerhalle tunnel are now being planned. Procurement of services is expected to take place in 2023.

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.

EXPEDIENCY ASSESSMENT 2. TRAMWAY AXIS BERNE CITY CENTRE

Today, the entire tram traffic in the historic center of the city of Berne is concentrated on the Marktgasse and Spitalgasse route. This section connects the eastern and western parts of the tramway network. A second tram route is expected to reduce the strain on the central network segments and to increase the operational reliability.

Berne’s historically grown tramway network is focusing on the central railway station. All feeder lines in the station area are using a single corridor, passing through Marktgasse and Spitalgasse in the upper part of the old town and thus through a central area of the UNESCO World Heritage perimeter. As this main axis is at the same time the most important shopping street in Berne’s historical center, conflicts with pedestrian traffic and supply logistics are inevitable.

With the planned construction of a new tramway line to Ostermundigen, the unsatisfactory situation will become even worse. After completion, this network section will have to accommodate 46 trams and 12 busses in each direction during peak hours. To alleviate the strain on the main axes and to establish a network less prone to operational limitations, plans for a second tramway axis between the central railway station and the “Zytglogge” clock tower are prepared.

R+R developed proposals for the alignment of the second axis as part of an expediency assessment, offered technical support and evaluated the layout options. The optimal solution suggests an alignment through Speichergasse and Nägeligasse. This would result in a substantial reduction of strain on the existing axis and, in the event of an incident, would allow for the rerouting of all tram lines onto the new route. In addition, R+R examined alternative options to infrastructure extension and developed possible measures to optimise the existing network and improve operational efficiency.
