The Bayview Bridge is a cable-stayed bridge bringing westbound U.S. Route 24 (US 24) over the Mississippi River. It connects the cities of West Quincy, Missouri and Quincy, Illinois. Eastbound US 24 is served by the older Quincy Memorial Bridge.
The bridge was built at a cost of $32 million, $3 million over budget, to alleviate traffic over the downstream Memorial Bridge. It was built before the extension of Interstate 72 (I-72) west into Hannibal, Missouri. Traffic levels increased when the existing, downstream US 36 bridge over the Mississippi River was closed to make room for the new I-72 bridge.
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, and remains structurally sound.
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.
