A8 Interlaken-Ost – Brienz: Renovation in progress

 A8 Interlaken-Ost – Brienz
The A8 between Interlaken-Ost and Brienz is undergoing a complete renewal.

The complete renovation of the A8 between Interlaken-Ost and Brienz is in full swing. Most of the work takes place at night. The construction site is set up every evening and cleared early in the morning so that the A8 is open to traffic again during the day. The night closures are expected to last until the end of 2024.

Addi­tional work zones with con­struc­tion during the day will be installed in multiple places. There, traffic will be reduced to one lane. Traffic lights will direct the vehicles one direc­tion at a time.

Despite the waiting times, the A8 remains the fastest way between Interlaken and Brienz. Divert­ing onto the cantonal road on the other side of the lake leads to a longer travel time and puts a strain on the local population.

Night closures

From 2021 to 2025, the A8 between Interlaken-Ost and Brienz is being completely renewed, including the tunnels Sengg, Chüebalm and Giessbach. To execute the work, the A8 is closed during the week as follows, depending on the season:

  • October to Mai: in the nights Mon/Tue to Fri/Sat from 8 p.m to 6 a.m.
  • June and September: in the nights Mon/Tue to Thu/Fri from 8 p.m. to 6 a.m., in the night Fri/Sat from 9 p.m. to 6 a.m.
  • July and August: in the nights Mon/Tue to Fri/Sat from 9 p.m. to 6 a.m.

Traffic between Interlaken and Brienz will be diverted onto the cantonal road on the right-hand side of the lake. The communal road will be available for traffic between Interlaken and Iseltwald.
