The bridge recently built across the Mississippi River at Clinton, Iowa, for 
the use of the Northwestern Railway is 3,650 feet, or more than three-fifths 
of a mile long. Of this distance 2,800 feet is between the Illinois shore and 
the Iowa shore. The bridge east of Little Rock Island consists of 14,000 feet 
of piling and seven spans of 200 feet each. West of Little Rock Island the 
bridge consists of three spans beside the draw. The draw is 800 feet long over 
all, and is built of iron. The abutment and one of the piers are founded on 
rock, a second pier is founded on piles, and a third pier and the draw pier 
are built upon cribwork, resting on loose sand. These cribs are sunk in water 
thirty feet deep. The large crib is 400 feet long and 44 feet wide on the 
bottom.  The draw turns on a pivot in the center and when open leaves two 
clear passageways for steam boat, 123 feet each. The draw weighs about 825 
tons.
