In 1853, the line was extended another 119 Miles to Geneseo, about 20 miles from the Mississippi River. This section crossed the Des Plaines River at Joliet and Fox River at Ottawa, and followed the Illinois River.
The remaining section of line was built in 1854, and went up to the Mississippi River.
The first railroad to reach west of the Mississippi was this one, as a swing bridge was built to cross the Mississippi in 1856.
However, the bridge became infamous for an accident in which the bridge collapsed after being struck by a boat. The lawyer who defended the young railroad? Abraham Lincoln, who would eventually become 16th president of the country.
The railroad renamed in 1880 to the Chicago, Rock Island & Pacific Railway, also known as the Rock Island.
The railroad operated this line heavily, extending it through Iowa towards Nebraska and the pacific. The line was the backbone of the railroad.
However, despite the seemed success of the railroad, it eventually began to fail. By 1980, the railroad fell to bankruptcy and abandoned all their property.
This line was purchased by the Iowa Interstate Railroad west of Ottawa, and CSX Railroad east of Ottawa to Joliet. Metra currently uses the Chicago to Joliet portion, for their Rock Island District.
Today, much of the line has been upgraded from the poor conditions it was at in 1980. It is operated as the CSX New Rock Subdivision east of Ottawa to Joliet.
West of Ottawa to Davenport, it is operated as the 1st Subdivision of the Iowa Interstate Railroad.
Located behind the Walmart in New Lenox, this tiny steel stringer bridge crosses a drainage ditch east of the nearby truss bridge.
Little is known about the bridge. It appears it was built around 1930, and consists of a single I-Beam span set onto concrete substructures.
Small spans like this were immensely common, as they were cheap and easy to build. This structure was built for two tracks, which it still maintains.
Overall, the bridge appears to be in good condition. It is apparent that the bridge has been regularly maintained.
The author has ranked this bridge as being minimally significant, due to the common design.
