This is my sixth installment visiting the bridges and structures of a
great American river. In this outing, we visit the bridges, locks, and
dams on the Missouri River. The mighty Missouri is the longest river
in North America, wandering from its source in western Montana and heading
south and east to its confluence with the Mississippi River at St. Louis,
Missouri. The river has three distinct sections. The lower river is
channelized to support river navigation. Through the Dakotas and eastern
Montana, the river is characterized by a series of monumental dams.
The river is much like a mountain stream from central Montana back to its
source at Three Forks.
In this installment, we look at the Upper Missouri River. We start at the
Fort Peck Dam in eastern Montana, and follow the river to just above Sioux
City, Iowa, which is the beginning of the lower Missouri River navigation
channel at mile maker 735.
