Preliminary measures on the A6 between Lyss-Süd and Schönbühl
R+R Burger und Partner is supporting the Federal Roads Office (FEDRO / ASTRA) as client-side project management support (BHU) and senior construction site management supervisor (OBL) in the N06.28 NEB EM Lyss-Süd–Schönbühl maintenance project. In this role, we are overseeing the preparation, coordination, and implementation of the preliminary measures – specific interventions carried out ahead of the main maintenance works. The objective is to upgrade the section for an additional 30 years of service life, thereby implementing ASTRA’s maintenance strategy.
As part of an advance measure (VoMa), nearly 2,000 manhole covers are being replaced on the highway section between Lyss-Süd and Schönbühl. Many existing covers have deteriorated to an unacceptable condition. In some cases, they can no longer be opened, which limits the ability to perform inspections and maintenance work on the infrastructure located below.
The affected manholes are used for road drainage as well as serving as inspection chambers and access points to the drainage systems and electrical installations. To replace them, the existing covers and the adjacent pavement will be removed during daytime construction work. The new covers will then be installed, sealed, and the pavement restored.
Work has been underway since July 27, 2026, and is expected to continue through the end of 2026. Temporary traffic restrictions are to be expected during construction. However, the A6 will remain open to traffic at all times.

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.

MOTORWAY MAINTENANCE PROJECT SCHLIEREN EXIT – EUROPA BRIDGE (GRÜNAU)
The short motorway section between Schlieren exit and Europa bridge is situated exclusively in a heavily urbanised environment. The four to six motorway lanes are complemented by two adjacent two-lane state roads, one on each side of the motorway. The corrective maintenance project for this motorway section and the refurbishment of the noise protection systems aim to take into account both cantonal and municipal design requirements.
The refurbishment and reshaping of the A1 motorway in the Grünau/Altstetten region near the western border of the city of Zürich covers a road section with a length of one and a half kilometres. In addition to noise protection, the reshaping of the road profile (including the installation of transparent noise barriers and the establishment of a median strip with tree rows) will result in a boulevard-like appearance and improve the motorway’s integration into the cityscape, thereby making the project a unique case. After a period of 30 years without any significant refurbishment measures, the renewal of the asphalt pavement, improvements to the drainage system, the construction of a road wastewater treatment plant and updates to the traffic management system are due. In addition to the operations on the motorway, changes to the motorway accesses necessitate adjustments to a number of communal roads and conduits, which requires close coordination with the City of Zürich and the respective municipal authorities.
R+R advises the Federal Roads Office‘s project manager in a staff function and will also provide construction site management. As this project includes road maintenance as well as conceptual improvements to an urban environment, advanced skills in the fields of project coordination and design are required in addition to conventional project management and controlling tasks.
