The major highways and bridges damaged during the June 2008 Midwest flooding and the 2005 Gulf of Mexico hurricanes, as well as the I-35W bridge, which collapsed in Minneapolis on August 1, 2007, are part of the federal-aid highway system and are therefore eligible for assistance under the Federal Highway Administration's (FHWA's) Emergency Relief Program (ER). Following a natural disaster or catastrophic failure (such as the I-35W bridge), ER funds are made available for both emergency repairs and restoration of federal-aid highway facilities to pre-disaster conditions.
