CERN’s new flagship building for science, education and outreach, designed by the Renzo Piano Building Workshop and Brodbeck-Roulet architectes associés, is entering its final construction phase.

The tubular structures that will soon house CERN’s exhibitions are connected by a bridge that passes over the Route de Meyrin at a height of 6 metres. The final phase of the work will require the installation of scaffolding around the bridge. To minimise traffic disruption, the scaffolding will be installed during the nights of 29, 30 and 31 August and 1 and 5 September between 10 p.m. and 5 a.m.

All motor vehicles will be deviated via the Rue Germaine Trillon (D35), which passes throughthe communes of Prévessin-Moens and Ferney-Voltaire in France, or via the Avenue Auguste-François-Dubois in the town of Meyrin in Switzerland. Public transport (i.e. the tram stops of lines 18 and 68) will remain accessible at all times, except from 1.00 to 4.40 a.m. Cyclists and pedestrians will not be impacted. Traffic officers will be present throughout the duration of the work.

Although every step is being taken to limit the impact of the work as much as possible, CERN wishes to apologise in advance for the inconvenience caused and to thank local residents for their understanding. Users are encouraged to drive with caution and to comply with the roadsigns that will be put in place.

CERN's Science Gateway will be an emblematic education and outreach facility. Through immersive exhibitions and hands-on educational activities, it will enable people of all ages and backgrounds to engage in the Laboratory’s discoveries, science and technologies.  

The Science Gateway’s buildings will host inspirational exhibition spaces, laboratories for hands-on scientific experiments for students of all ages and a large auditorium hosting events.
