Shaw, a case involving Federal authority to construct the Panama Canal, Supreme Court Justice David Brewer writes that based on Supreme Court precedents, "These authorities recognize the power of Congress to construct interstate highways" under the constitutional right to regulate interstate commerce. This decision effectively ends the debate over whether the Federal Government can fund road projects. |

It reveals that of the approximately 563,500 highway bridges in the U.S., about 88,900 are considered critically deficient. An estimated 24,000 of these deficient bridges are on the Federal-aid highway system. More that 400,000 of the Nation's bridges were built before 1935. |
