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 confluence with the Mississippi
River at St. Louis, Missouri, and heading north and west to its source
in western Montana. 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 begining of the lower Missouri River navigation
channel at mile maker 735.
Status—this section is largely completed except for photography
along the South Dakota and Nebraska border.
