The St. Francis River Bridge, also known as the Lake City Bridge, was a historic bridge spanning the St. Francis River at Lake City, Arkansas. It was composed of 109 I-beam trestles and a single vertical lift span, and had a total length of 3412 ft. The bridge was designed and built in 1934 by the Vincennes Bridge Company, and carried Arkansas Highway 18 until 1998, when a modern 4-span I-beam bridge was built adjacent to it. The old bridge was dismantled, leaving only the vertical lift segment on the east bank of the river.Wikipedia
