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 A1 EFFRETIKON – OHRINGEN
A 12 km stretch of the A1 motorway between the exits Effretikon and Winterthur Ohringen is to be refurbished. Moreover, by introducing up-do-date signalling technology, an optimisation of the traffic flow on the section Winterthur Töss – Winterthur Nord junction is to be achieved.
Stretching an approximate 12 kilometers in length, the A1 motorway section between Effretikon exit and Winterthur Ohringen exit ranks among the most congested motorway sections in the Swiss motorway network. The number of vehicles using it amounts to 100‘000 per day. The section in question has been in continuous service since 1974 and no significant restorative measures have been undertaken since then. In the context of the maintenance project «A1 Effretikon – Ohringen», the section is thus going to be refurbished in the coming years. In particular, there will be a renewal of parts of the roadway and the operation and security installations, in order to comply with current regulatory standards. Additionally, several adjacent structures require corrective maintenance measures to be carried out to warrant full operability of the constructions until the end of their expected life spans.
The FEDRO aims to effectuate a smoothing out of the traffic flow in the Winterthur area by installing up-to-date signalling technology. The project at hand will see to the implementation of according measures between the Winterthur Töss exit and the Winterthur Nord junction. Work on preliminary maintenance measures is set to begin in mid-May 2019. The principal part of the corrective maintenance will be carried out from 2020 to 2022. As part of a set of precursory measures, the Töss Bridge, the overpasses Zürcherstrasse Süd and Grafstal, three structures at the Effretikon exit, the retaining wall Pfahlwand Rossberg and the traffic light system Salomon- Hirzel-Strasse were refurbished between 2015 and 2017. Total project costs amount to 228 Mio. Swiss francs.
Holding mandates as project-owner support unit and construction supervisor, R+R supports and advises the general project management team of the Federal Roads Office in project management, controlling and the assessment of selected issues for the entire duration of the project.
