The useful question is what changes for users, developers or buyers, and whether the announcement stays industry context or becomes something people can actually use.

Starting 31 August 2026, Gate B will undergo phased closures until 7 February 2027, with full and partial closures affecting vehicle, pedestrian, and cyclist access. During Phase 4, Gate B will remain open for exit only from 11 November 2026 to 7 February 2027. The current bus stop at B300 will be relocated to B39, and the bicycle station near B120 will move to B124. Temporary adjustments will be communicated in advance.

Phase 2 will involve closing the junction between Route Pauli and Route Einstein, requiring drivers to use a diversion via Route Democrite and Route Rutherford. Temporary traffic signs will guide road users during this period. Access to B55 from Gate B will be unavailable throughout the works, though B55 will remain reachable via B56.

The works will proceed in multiple phases, with dates subject to minor adjustments based on construction progress and site conditions. Additional details and reminders will be published before each major phase begins. The SCE Department will provide further information on its dedicated website.

CERN advises all visitors, employees, and contractors to plan ahead and monitor updates for changes to access routes and schedules. The adjustments aim to maintain site accessibility despite the ongoing construction activities.
