The Quincy Memorial Bridge is a truss bridge over the Mississippi River in Quincy, Illinois. It brings eastbound U.S. Highway 24 into the city of Quincy from Missouri. It was built in 1930, initially as a toll bridge,[http://www.modot.org/newsandinfo/publications/documents/1930.pdf Map of Missouri Showing State Road System], January 1, 1930 and remains structurally sound.

Building of the bridge began in 1928 by the Kelly-Atkinson Company. It was completed in 1930, with the first car crossing the bridge on May 19 of that year on an official inspection trip. Although the original toll for the bridge was 50 cents, by 1945 the city had paid the outstanding bonds which financed the bridge's construction, and the fares were eliminated.{{Cite web|date=2013-02-10|title=How Memorial Bridge was built|url=http://www.hsqac.org/how-memorial-bridge-was-built|access-date=2021-02-18|website=www.hsqac.org|language=en}}

In 1986, to serve additional traffic volumes crossing the Mississippi River into Quincy, the Illinois Department of Transportation constructed the Bayview Bridge just to the north of the Memorial Bridge. Westbound traffic was then routed onto the Bayview Bridge, while eastbound traffic was routed onto the Memorial Bridge.

Since 2012, demolition and replacement of the historic Memorial Bridge with a more modern one is being considered by the Illinois Department of Transportation to cope with increased traffic demands on the aging bridge.{{Cite web|date=2013-02-10|title=How Memorial Bridge was built|url=http://www.hsqac.org/how-memorial-bridge-was-built|access-date=2021-02-18|website=www.hsqac.org|language=en}}{{Cite web|title=Quincy Riverfront Master Plan|url=https://storymaps.arcgis.com/stories/3c1b00242ee54a55a72aba518f6d9595|access-date=2021-02-18|website=ArcGIS StoryMaps}}{{Cite web|title=Quincy Mem Bridge - CAG Meeting 2 Documents|url=http://www.quincymemorialbridge.com/docscag3.html|access-date=2021-02-18|website=www.quincymemorialbridge.com}}
