Most bridges are compromises: Cars want to speed low and straight across the water, but but boats want to pass under them. So we wind up with either tall bridges (expensive) or moveable bridges (clunky and awkward). But now a Dutch engineering firm has come up with a radical solution that doesn't involve the bridge—instead, it lowers the water 26 feet to let ships safely pass.
