Texas Street Bridge at night

Why did they decide to put tube lights on the Texas Street Bridge, and where are these lights getting their power? And when the bulb goes out, who is in charge and says, “It’s time to change the bulbs”? I am curious about these things, but one thing is for sure, this bridge at night-time is definitely one of the more visually interesting things that Shreveport-Bossier has to offer. From the I-20 bridge, it looks like rods of light hanging in the air. I remember being really small and asking my mom about thelight-up bridge, only the colors of the tube lights were all different colors then, and now they are mostly that red-orange color. So why did they decide to go to one color? Didn’t the many colors make the bridge much more interesting? I think it did. So why did they bland it up? SOMEONE ANSWER MY QUESTIONS.
