Mark N. Norris Bridge

The Mark N. Norris Bridge is a steel truss structure that crosses the Mississippi River between Clinton, Iowa and Fulton, Illinois. The two-lane roadway carries traffic in both directions across the river's substantial width.

The current bridge was built in 1975, replacing an earlier wooden structure from 1891 that had been reinforced with steel grating decades before. This new construction permanently modernized the connection between the two states.

The bridge serves as a daily crossing point for people living on both sides of the river, connecting two distinct communities. It has become an ordinary part of life for residents who use it without thinking much about the state line they cross.

The bridge is open to regular vehicle traffic at all times and offers direct access from both sides of the riverbank. There are areas where you can stop briefly to view the river and surrounding landscape if you wish to take a moment.

In 1982, tolls for crossing were completely eliminated, making the bridge free for all users. This decision allowed both states to share the management and maintenance responsibilities equally.
