This two lane road tunnel of approximately 100 metres length passes underneath the Philharmonie Luxembourg concert hall. It leads from Rue J. F. Kennedy, descending slightly, to a futuristic building with an undulating overhanging ceiling, where it ascends again to the light of day. The tunnel is a dead-straight tube, pierced only by parking and delivery areas and ramps belonging to and/or leading to the adjoining hotels and the Philharmonie. A premium grade lighting grid ensures that the tunnel is perfectly lit. Everything seems modern, clean and safe, there is nothing forbidding about this place. The clean, contemporary vibe of the tunnel is continued above ground, when, upon exiting, drivers see the sumptuous facades of the sophisticated, new office buildings and hotels. Excellent infrastructure.
