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.

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.
