EP Hagnau – Augst N02
Within the Hagnau – Augst motorway maintenance project, structural changes to the western tunnel portal (direction Basel/Germany) have to be carried out to enable longitudinal ventilation in both traffic directions. We are pleased that the plans for the extension of the western portal of Schweizerhalle tunnel have officially been approved. This allows us to finalise the detailed design and approach the contractor submission process according to our project schedule.
N06.28 NEB EM Lyss Süd – Schönbühl
We are pleased to provide managenent support and construction site management for the N06.28 NEB EM Lyss Süd - Schönbühl motorway maintenance project on behalf of the Federal Road Authority’s Thun branch. The project includes replacement of the pavement as well as extensive measures on the engineering structures. The construction work is scheduled to be carried out between 2025 and 2027.
A1 Opening day of the Gubrist tunnel
Another bottleneck removed: On July 3rd, Federal Councilor Albert Rösti officially opened the new third tube of the Gubrist motorway tunnel, in the presence of representatives of the canton and city of Zurich as well as the local communities and members of the project team. Now three westbound traffic lanes are open to road users travelling in the direction of Bern.

Aarwangen Traffic Improvement – NISTRA Assessment
| In the future, through traffic will bypass Aarwangen on a new road west of the town. The NISTRA evaluation tool, developed by the Federal Roads Office, is used to assess the advantages, disadvantages and costs of the project. The high volume of traffic on the main road through the town of Aarwangen affects residents and leads to congestion. A new western bypass road will divert through traffic around the town. This will relieve the pressure on inhabitants of the town center, obstructions to slow-moving traffic and public transport will be reduced, and traffic safety will be improved. In addition, the main road through town can be made more attractive. The Department of Civil Engineering of the canton of Bern commissioned R+R to evaluate the bypass project using the NISTRA evaluation tool developed by the Federal Roads Office. The advantages and disadvantages of the project are analyzed, benefits quantified and costs determined. NISTRA combines three different assessment approaches (cost-benefit analysis, cost-effectiveness analysis, qualitative analysis). In addition to Aarwangen itself, the assessment also takes the neighboring communities of Langenthal, Thunstetten and Bützberg into account, as these will also be affected by the changed traffic flows. NISTRA yields a positive overall rating considering environmental, economical and social factors. Even with a negative rating on some aspects concerning environment and spatial development, the positive project effects predominate. The focus is on the benefits of shorter travel times, improved access, a safer traffic flow and less noise and exhaust emissions for residents. |
