The flapping of dozens of pairs of wings. The hum of passing traffic. The heavy rumble of a train as it passes overhead.
If you've never heard what a train sounds like from under a bridge, I wouldn't say I'd recommend it. Personally, it seems to resemble rolling thunder, if the thunder were sounding through a megaphone, mere inches from my ear. In my humble opinion, the ruckus is so anxiety inducing, it sends a shiver down my spine every time that I'm forced to hear it and I pray to any god willing to strain its ear through the static, to keep my soul intact.
In the moments before the train rolls by, I can feel it, the sound, building under my feet. In the moments after the train has stopped and the noise has paused, I take a deep breath and hold it. As the train bellows away, wheels screeching against the rails, cars click-clacking back and forth overhead, I exhale and shake it off.
It's a noise so loud it burrows into skin and radiates through bone. A noise so loud I can taste it. Copper and dry mouth, like cotton stuffed under my lips and pennies stuck between my teeth...
I really can't stand waiting for the bus under here.
