St. Francis River Bridge, Vertical-lift bridge remnant in Lake City, Arkansas, United States

St. Francis River Bridge, also known as the Lake City Bridge, was a 3,412-foot (1,040 m) crossing of the St. Francis River at Lake City, Arkansas. It consisted of 109 I-beam trestles and a single vertical lift span, designed and built in 1934 by the Vincennes Bridge Company. Only the vertical lift segment remains on the east bank after the bridge was dismantled.

The Vincennes Bridge Company designed and built the bridge in 1934, and it carried Arkansas Highway 18 until 1998. That year a modern four-span I-beam bridge opened next to it, and the old structure was dismantled, leaving only the vertical lift segment on the east bank. It was listed on the National Register of Historic Places in 1990.

It served as a vital link for communities on either side of the river and became part of the daily rhythm of local life. Crossing it connected people to jobs, markets, and family across the water in an era when such bridges were gateways between isolated areas.

Only the vertical lift span remains, standing on the east bank of the St. Francis River; the rest of the 3,412-foot bridge was dismantled after 1998. Arkansas Highway 18 now crosses the river on the modern four-span I-beam bridge built alongside, so the remnant is viewed from the bank rather than walked.

Of the original 3,412-foot structure, only the vertical lift span survives, standing on the east bank after the rest was dismantled. The 109 I-beam trestles that once carried Arkansas Highway 18 are gone, so the remnant marks where the road crossed before the 1998 replacement opened.
