October, 2012

Shinminato Bridge is located in Imizu, Toyama Prefecture, was recently opened in September 2012. It is the largest cable-stayed bridge on the Sea of Japan coast, and links the east and west districts around the Toyama Shinminato Harbor entrance. It boasts an enormous scale with an overall length (including the arch sections) of 3.6km, a 600m main bridge section above the water, and main bridge-support towers 127m high. The bridge girders are suspended 47m above the surface of the ocean, allowing even large vessels smooth passage underneath. One of its spectacular design features is its twin-level structure, which features a 2-lane road roughly 50 meters above sea level and a road for bicycles and pedestrians beneath that (the bicycle/pedestrian road is scheduled to open in the spring of 2013). The bridge is lit up in a uniform white, and seems to float magically ‒ with a sharp and elegant profile that is still in harmony with its surroundings. The initial lighting design contemplated the use of HID lamps, but the introduction of LED lighting was investigated in order to aim for a lesser burden on the environment through reduced CO2 emissions and reduced maintenance/management costs from long operating lives and low power consumption. A decision was made to use high-output LED floodlights roughly a year ago, and they were installed after some on-site testing. The bridge is popular as a new symbol of Imizu, and is hoped to see much use by many in the future.
