On 25 June, the TEB welcomed a delegation from the Tempelhof-Schöneberg District Office as part of an exchange on cross-border cooperation.

Since March 2026, the 3Land programme has welcomed a pair of project managers (trilingual in French, German and English) who specialises in project management as well as cross-border and intercultural cooperation.

A new Rhine bridge between Huningue and Basel is a key element for cross-border mobility in the 3Land area. Starting in 2026, its technical, legal, and financial feasibility will be examined in depth to enable informed decisions on subsequent planning steps.
