Leading Infrastructure for Tomorrow's America Act This bill reauthorizes a variety of programs and creates new programs for infrastructure development, including communication, drinking water, energy, or health care infrastructure. The bill provides support for communication infrastructure, such as funding to expand broadband internet access, or implement next generation 9-1-1 systems.
