The Marr's Creek Bridge is a historic bridge spanning in Pocahontas, Arkansas. The concrete open spandrel deck arch bridge formerly carried U.S. Route 67 (US 67), which now passes over the creek on an adjacent modern steel and concrete structure. When built in 1934 by the Public Works Administration, the bridge had a total length of 135 feet (41 m), with six spans, including the main arch across the creek. The bridge was widened slightly at its eastern end in 1950 to accommodate a slight curve. The bridge was listed on the National Register of Historic Places in 2008.
