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.

MOTORWAY MAINTENANCE PROJECT LIMMATTAL INTERCHANGE – SCHLIEREN EXIT
The 30-year old Limmattal interchange – Schlieren exit section of the A1 motorway features six lanes and has a length of five kilometres. Within the framework of the Federal Roads Office‘s maintenance planning program, extensive refurbishment was undertaken in 2013 and 2014.
Operations within the corrective maintenance project encompassed the refurbishment of the pavement, adjustments to the guidance and protection systems, the provision of new cable conduit blocks, as well as corrective maintenance on structures and drainage systems. Various maintenance measures were carried out on pavement, bridge deck, shoulder curbs and sealings of the Limmat bridge, while expansion joints and bearings were replaced. Several under- and overpasses were refurbished as well. These construction measures allow for an additional 15 to 20 years of service, without any further intervention required.
A subsequent project phase will include the construction of a new road waste water-treatment plant close to the Oberengstringen service area. It is also planned to adapt the exit lane leading to the service area in order to comply with current technical standards, as well as to add electric cabinets.
R+R supported the project management team of the Federal Roads Office by providing comprehensive project management services. These included the procurement of multiple planning mandates and the submission of the construction works, project controlling of current contracts, cost monitoring and –planning as well as construction site management.
