The Sound Tube on Melbourne’s Citilink Tollway is supposed to reduce the noise from the freeway to the high rise apartments located to the west of the elevated road. The western wall of the Sound Tube is solid whereas the rest of the construction is an open mesh.
I LOVE this structure and I love driving through it.. I always just think of it as the Whale Bridge.
Took this from a convertible with the camera above my head :).
