Missouri is bounded by Iowa on the north; by Illinois, Kentucky, and Tennessee across the Mississippi River on the east; on the south by Arkansas; and by Oklahoma, Kansas, and Nebraska (the last across the Missouri River) on the west. Whereas the northern and southern boundaries are straight lines, the Missouri Bootheel protrudes southerly into Arkansas.

With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and 2 Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth - longest and fifteenth - largest river in the world by discharge. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Document 6: Bridge in East Fallowfield Township (Mortonville, Pennsylvania): The Mortonville Bridge and Mill Race Bridge are stone arch bridges carrying Strasburg Road across the West Branch Brandywine Creek and an abandoned millrace at Mortonville, Pennsylvania.
