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 ROADWAY MAINTENANCE PROJECT BRÜTTISELLEN INTERSECTION
The Brüttisellen intersection links the A1 with the A53. The heavy volume of traffic leads to regular jams. Due to the poor condition of the two dual bridges, repairs are required in advance of the comprehensive renewal of the Zurich East – Effretikon section.
The Brüttisellen intersection was built in 1974. The Haldenbrücke bridge and the underpass for the connecting road are reinforced concrete composite bridges with lengths of 184 meters and 86 meters respectively. The choice of the foundation in difficult, non-homogeneous subsoil deliberately took account of differences in the settlement of the abutments and supports. The settlement differences are compensated by removing washers. For this compensation to remain possible, the bridges had to be raised to their original levels in 2012/2013. Due to the high volume of traffic, the condition of the two bridges requires reinforcements for the steel girders and total renewal of the corrosion protection. Traffic safety was improved by adjustments to the traffic routing in the area of the entrance to the A1 in the direction of Zurich.
The refurbishment work was brought forward in response to the results of the structural engineering investigations. The comprehensive repair and renewal of the Zurich-East to Effretikon section of the national highway is scheduled between 2025 and 2030. R+R provided assistance for the overall management of the project by the Federal Roads Office (FEDRO), Winterthur Branch, by way of client support during the implementation of the project. Key aspects of this support included procurement, meetings and project controlling. R+R was also entrusted with quality assurance by the client. High-quality documentation and professional dealings with external parties, together with plans and reports that are error-free and consistent insofar as possible, are prerequisites for the efficient provision of services, a high quality of execution and minimal additional costs due to changes and adjustments to specified requirements for building contractors.
