We, the bridge maintainers of America hold these truths to be self-evident: all
joints leak, all concrete cracks, and rust never sleeps. We will strive to capitalize
our way out of maintenance and maintain our way out of capital. It is our endeavor to educate others that a bridge
is as important to a highway as a diamond is to a ring.
