Great River Bridge

The Great River Bridge is a cable-stayed structure spanning the Mississippi River with a single tower that rises 370 feet above the water and connects Illinois with Iowa across five traffic lanes. The structure runs along U.S. Route 34 and accommodates both vehicles and pedestrians traveling between Burlington, Iowa and Gulfport, Illinois.

Construction began in 1989 and the bridge opened in 1993, replacing an older 1917 structure that had developed structural issues. The previous crossing had become inadequate for the region's transportation needs.

The structure connects two states and hosts an annual May race that brings nearby communities together in celebration. This event shows how the bridge has become a gathering place that matters to the people on both sides of the river.

The bridge is easily accessible from both sides and accommodates different types of traffic on its lanes. Visitors should expect normal conditions during the day, though local events like the annual race can affect traffic flow.

The bridge's foundations extend 90 feet deep into bedrock, showcasing advanced engineering techniques. This deep anchoring protects the structure from the river's powerful currents and the region's weather conditions.
