One of the characteristics embedded in the program is that the federal government is not the sole funder for projects. We provide a percentage of funding and our funding has been able to leverage funding from other sources, be it public sources or private sources.
Through the $4 billion that the federal government has invested, we have been able to leverage over $10 billion overall. I think that really has made these investments go much farther, but it also just makes sure that we're working very closely and collaboratively with our partners in the transportation system.
