NEXCO EAST Yuzawa Management Office (Yuzawa Town, Minami Uonuma District, Director: Kazuhiko Haruyama), the Kan-Etsu Expressway Kanetsu Tunnel (extension of about 11 km) was changed to a fluorescent light at the exit side of about 3 km as the tunnel lighting deteriorated and renewed. I will let you know.

Conventionally, energy-efficient and economical sodium lamps have been used in road tunnels, but due to technological advances in recent years, high-output, high-efficiency, long-life fluorescent lamps have been developed. We are recommending the application in the tunnel.

This is the first time that fluorescent lighting is used in a Expressway tunnel in Niigata Prefecture.

In this fluorescent lighting section, it is expected that the electricity cost for tunnel lighting will be saved by about 30% compared to before the renewal, which is about 60t of CO annually. ₂ Equivalent to reduction.

We apologize for any inconvenience caused by lane restrictions during construction, but we ask for your understanding and cooperation as it is necessary to ensure safe and comfortable driving on the Expressway.
