Pueblo Levee Mural Project, Public art project along Arkansas River levee in Pueblo, United States

The Pueblo Levee Mural Project covers a concrete levee of the Arkansas River in Pueblo, Colorado, with a continuous painting certified by Guinness World Records as the longest in the world. The painted surface runs for 3 miles (about 4.8 km) along the embankment.

Students at Colorado State University–Pueblo began painting over graffiti on the levee at night in the 1970s to avoid police notice. The work gained community support, and in 1988 a dedicated coordinator was appointed. By 2014 the 90-year-old levee was bulging and cracking and needed resurfacing, which would have destroyed the mural.

You can access this project through walking paths along the Arkansas River, with several entry points and parking areas near the riverwalk. The best time to visit is during daylight hours when you can see the artwork details and colors clearly.
