The Government Bridge, also known as the Arsenal Bridge is a double -deck swing bridge and truss bridge in the United States, located on the border of the states of Iowa and Illinois. The bridge spans the northern (main branch) of the Mississippi River in Davenport.
Characteristics
The bridge is a double-deck steel truss bridge with 8 spans. The fixed spans are 79 meters long, the main span is a swing bridge on the Illinois side over the locks and is 111 meters long. The swing bridge can rotate 360 degrees, so during a full opening cycle the bridge turns the other way around. The bridge is a total of 490 meters long, making it one of the shortest bridges over the Mississippi River.

The bridge connects the city of Davenport in Iowa to Arsenal Island in Illinois, and indirectly to Rock Island, Illinois. The bridge is toll-free.
History
Because of Arsenal Island, the Mississippi River at Davenport was narrower than at other locations, and therefore suitable for a bridge, the first railroad bridge over the Mississippi River was built on the site in the 1850s. This bridge was slightly upstream from the current bridge. The bridge opened to rail traffic on April 22, 1856. This bridge only lasted 10 years, in 1866 a second bridge was built over the existing bridge piers that could handle heavier trains. This bridge lasted even shorter and was replaced in 1872 by an iron double-deck bridge on new bridge piers.
The current bridge was the fourth bridge across the Mississippi at Davenport and opened to traffic in 1896, using the bridge piers from the 1872 bridge. The bridge was designed by noted Polish-American engineer Ralph Modjeski. The bridge was renovated in 1983 and 1997. The bridge has the status “functionally obsolete”, which means that it no longer meets the current design requirements, although the condition is still sufficient.
Traffic intensities
About 17,000 vehicles cross the bridge every day.
