Summary
[edit]DescriptionBay Bridge at night 2.jpg |
English: Upper deck of San Francisco – Oakland Bay Bridge at night.
The illuminations on the cables, while part of the original design, are actually a relatively recent addition, made practical by the availability of high efficiency compact fluorescent lamps. The original roadway illumination was by low pressure sodium vapor lamps, which while efficient give off a garish monochromatic yellow light. On the lower deck these have been replaced with tubular fluorescent lights attached to the bottom of the upper deck, while on the upper deck the illumination is by high pressure vapor lamps, which give off a more full spectrum light.日本語: サンフランシスコ・オークランド・ベイブリッジ.
