"The Keokuk Bridge, also known as the Keokuk Municipal Bridge, carries a double deck single track railway and highway bridge across the Mississippi River in the USA between Keokuk, Iowa and Hamilton, Illinois, just downstream of Mississippi Lock and Dam number 19. It was designed by Ralph Modjeski and constructed 1915–1916 on the piers of its predecessor that was constructed in 1869–1871.
"Following the completion of the Keokuk-Hamilton Bridge, the upper deck of this bridge, on the Keokuk side, was converted to an observation deck to view the nearby lock and dam; this deck is no longer used for road traffic, but is still used for rail traffic. The bridge was originally owned by the Keokuk & Hamilton Bridge company, but following financial problems in the 1940s, the bridge was given to the City of Keokuk in late 1948.
"The bridge was originally the western terminus of the Toledo, Peoria & Western Railroad. Today, it serves the Keokuk Junction Railway with an occasional train crossings for interconnection and river terminal services. Only the Keokuk side of the highway bridge has been converted, the bridge's upper highway deck is abandoned. The river traffic (barges and boats) have the right-of-way, so the swing section remains open until a train needs to cross the river.
"It is documented in the Library of Congress Historic American Engineering Record as survey number IA-3." ~ Wikipedia

Where today
and History Meet
The city of Keokuk has long been associated with thriving commerce and transportation even before it was incorporated in 1847. The location of the Des Moines Rapids in the Mississippi River made it necessary for steamboats to unload passengers and freight and arrange for portage around the rapids. Packets, excursion boats, tows, and rats navigated up and down the river stopping at Keokuk along their way.
Many businesses flourished at the foot of these rapids making the settlement a major stopping off point for people and products continuing up the river or being transferred to prairie schooners that transported goods to interior areas.
Most of the earlier commerce was carried on around the "levee", at the foot of Main and Johnson Streets, and in an area called "Rat Row." At this time the city had not expanded up the timber covered bluffs above the river.
Another natural barrier was the Mississippi River itself and attempting crossing from east to west was sometimes hazardous. The ferry "Salina" was one of the local boats that carried passengers as well as freight across to the opposite banks. In the winter crossings were made on the ice with sledges and sleighs.
Consequently, in 1866 the Keokuk & Hamilton Mississippi Bridge Co. was formed with the construction beginning in 1869 and continuing for two years until April of 1871. This was the first combination roadway and railway bridge built across the Mississippi River. The construction contact was awarded to the Keystone Bridge Company of Pittsburgh which was one of Andrew Carnegie's first business ventures at a cost of $850,000.
The new "Iron Bridge" furnished another link for commerce between east and west and for freight and immigration. It was said that this bridge was one of the wonders of the nineteenth century - at least to the people of Keokuk. The total length of the bridge was 3800 feet and accommodated railroad cars, horse and wagon teams, and foot passengers.
Keokuk was the terminus of five different railroads: the Toledo, Wabash & Western, the Toledo, Peoria & Warsaw, the Keokuk & St. Louis, the Keokuk & St. Paul, and the Des Moines Valley Railroad. A locomotive named the "Iowa" was the first to cross the Keokuk - Hamilton Bridge on April 19, 1871. The bridge was opened to the public on June 14, 1871.
In 1916, the bridge remodeling project was completed adding an elevated roadway that accommodated wagons, automobiles and pedestrians. Today, the old iron bridge is used for trail traffic on the loser level while the upper level road is used for an observation deck allowing one of the finest views of Lock and Dam #19, the Keokuk hydro-electric plant, the Geo. M. Verity Riverboat museum and the Keokuk Union Depot.
