The railroad was immediately incorporated into the Chicago & North Western Railway, which connected at Nelson.
By 1913, the railroad was pushing for expansion, and the St. Louis, Peoria & Northwestern railway built an additional 90 miles.
The expansion crossed through Springfield and connected at Girard. The C&NW purchased the railroad.
The C&NW used this as a heavy mainline, connecting St. Louis to Chicago, Springfield and Peoria. It also was used for coal mining.
By 1995, the Chicago & North Western was purchased by Union Pacific. The line from Girard to Barr was abandoned in 1998.
Presently, the Union Pacific calls the Barr to Nelson segment as their Peoria Subdivision.
Located near Green Valley, this large truss bridge crosses the Mackinaw River parallel to IL-29.
Built in 1913 as part of a new line, the bridge features a single Quadrangular Through Truss, approached by a girder on the north side. Originally, these two spans were approched by trestle, however the north approach has been replaced with I-Beams. The bridge rests on concrete, steel and wood substrcuctures.
While nationally the Quadrangular design is uncommon, it was popular with midwestern railroads, particularly the Chicago & North Western.
The builder, King Bridge Company, is also not known to have built many Quadrangular trusses. The only ones known to exist are this one, and the large lift bridge approximately five miles north of here.
Overall, the bridge appears to be in fair to good condition. The author was not able to inspect under the truss, where other nearby similar bridges have been found with serious deterioration.
The author has ranked this bridge as being moderately significant, due to the truss design.
