President Millard Fillmore signed the land grant for the new rail line in 1850, making it the first Land Grant railroad constructed.
The first parts of the line were built south from Freeport. The line from Galena to Freeport was a portion of the original Chicago & Galena Union Railroad.
Construction began in 1851, and the line reached Cairo by early 1856. Upon completion, the road was the longest in the world. It would be named the Illinois Central.
The railroad backbone of Illinois also had many connections. At Centralia, a line branched towards Chicago. At Cairo, the line continued south via steamboat to New Orelans.
The northern section of the line ran from Bloomington/Normal to Galena, and up to the Mississippi River. The final 15 miles in Illinois opened in 1870, as part of the line into Iowa.
The line ran into significant obsticals. Near Galena, the terrain is some of the most rugged in Illinois, meaning the railroad had to use various vallies to build through the area.
At La Salle, the Illinois River is a signficant barrier, and a bridge nearly half a mile long was required.
Freeport also became a major stop as the Illinois Central. In the 1880s, a line would be added to Madison, Wisconsin; as well as to Chicago.
Bloomington, La Salle, Mendota and Dixon also were major stops; crossing various railroads heading into Chicago.
The line had a stable traffic base, and in 1972, the Illinois Central became the Illinois Central Gulf, after a merge with the Gulf, Mobile & Ohio.
Despite the lines significance, the segment from Freeport to Centralia was abandoned in 1985. However, exceptions existed.
The Illinois River Bridge at La Salle, and track as far south as Oglesby were purchased by a gravel mine, Buzzi Unicem; who owns and operates it now.
The remaining portions of the line are owned by Canadian National, although Illinois Central is still an active subsidiary.
The remaining portion from Galena to Freeport is the Freeport Subdivision.

Located north of Forreston, this large stone arch bridge crosses the Leaf River.
Built in 1851 during the initial construction of this route, the bridge features a single stone arch span. This span is of standard design.
While Illinois doesn't have a ton of very old stone arches, the Illinois Central built numerous arches of this type between 1850 and 1855, making these some of the oldest remaining arches in the state.
Overall, the bridge appears to be in excellent condition. These arches are notable for the exceptional durability they demonstrate.
The author has ranked this bridge as being moderately significant, due to the old age.
