Welcome Maria Jose Hernandez Guevara
We are delighted to welcome Maria as a new member of the R+R staff and wish her every success in her new role.
Maria holds an MSc in Civil Engineering (Geotechnical Engineering/Construction and Maintenance Management) from ETH Zurich, as well as a BSc in Civil Engineering (Honours, cum laude) from the Universidad de Los Andes in Bogotá, Colombia.
Thanks to her many years’ experience in client representation, tunneling and underground construction, procurement, and operational and strategic project management, she is an excellent addition to our R+R-Team’s consultancy and technical expertise.
N11/60, N01/42 UPlaNS – ZH-Ost–Kloten Süd Interchange (ZOK), Completion of the Maintenance Concept (EK) Phase
Renato Käppeli / Stefan Isler
Over the past two years, we have supported the Federal Roads Office (FEDRO) as project-owner support unit in the development of the maintenance concept (EK) for the ZOK project.
In addition to renewal work, smaller, targeted improvements to enhance traffic safety and traffic flow were also examined.
A particular challenge in this demanding project was the dense population and high traffic volume in the vicinity of Zurich Airport.
Approval for the EK has been granted, and we look forward to supporting the next project phases.
N06.32 EP Muri – Rubigen
On April 23rd, 2026, the Federal Department of the Environment, Transport, Energy and Communications issued planning approval for the "N06.32 EP Muri – Rubigen" maintenance project on the A6 motorway to FEDRO’s Thun branch. If no objections are received, the next phase of the planning process can be started. Actual maintenance work on this section of the motorway as well as on the Worb feeder road will be carried out from 2029 onwards.
N08 EP Sarnen South – Hergiswil
On the northernmost section of the N8, which forms part of the important transit axis between Central Switzerland and the Bernese Oberland, extensive renovation work is planned for the coming years on the route, engineering structures, and operational and safety facilities. We are delighted to be supporting the Zofingen branch of ASTRA as the client's representative in this project.

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.
