An announcement came in 1855 that a railroad was to cross the Mississippi, South of Lyons, at Little Rock Island. At the same time, the Iowa Land Company (ILC) was formed. The ILC purchased Bartlett's tract on the Iowa shore opposite Little Rock Island. Concurrently, the Chicago, Iowa, & Nebraska (C&IN) Railroad was formed, with the express intent of crossing the Mississippi River at Clinton. Construction on the railroad bridge began in 1856, and Clinton's population grew to over 1,000 as construction continued. In June 1859, the railroad line was completed toCedar Rapids. The first train crossed from the Illinois shore to Little Rock Island at noon, January 9, 1860, and was ferried from there to the Iowa shore. In January 1864, construction was started on the span from Little Rock Island to the Iowa shore and was completed on January 6, 1865. The original single track railroad bridge was replaced by a double track bridge that was completed in 1909.
