Under the Freeway Bridge

This sound is of passing cars under the freeway bridge. I could hear the cars driving fast above me and besides me. It makes me think how everyone is always in a rush to get everywhere. By everyone I also mean myself. I never seem to stop and actually see and hear what is around me. I always walk under this freeway bridge but I have never paid much attention to the sound. After hearing the sound clip again I realized it sounded like the sound was something from underwater. It was interesting to me because it made me think of how the sounds of the cars zooming under the bridge and above, plus the wind can make a whole different sound.
