In 1889, the Chicago, Rock Island & Pacific Railroad sought to connect the end of their Council Bluffs-Chicago mainline at Council Bluffs to Lincoln, Nebraska and eventually to a point southwest near Fairbury, Nebraska; where the Chicago, Kansas & Nebraska Railway (CK&N) had built in 1887. Because the CK&N had built a considerable network of routes around Kansas, Nebraska and Colorado; this connection was desired to give the Rock Island access to Denver. The Rock Island purchased the CK&N in 1891. Trackage rights were secured to cross the Missouri River on the Union Pacific Bridge into Omaha, before the route turned southwest, running through Papillion and Richfield, before crossing the Platte River at South Bend. From here, the route continued through Murdock, Alvo and Prairie Home. By 1892, the Rock Island had reached Lincoln, passing through the east side of the city. In 1893, work continued south, and the route was built through Rokeby, Hallam, Clatonia, DeWitt and Plymouth before finally reaching the existing line at Jansen, Nebraska. The Rock Island was a poor railroad, facing financial trouble
regularly and often in bankruptcy. This route hosted passenger trains
known as "Rockets" for many years, although passenger trains were later
discontinued. After World War II, the Rock Island struggled to survive,
proposing mergers and deferring maintenance on their routes. Rock
Island sought to keep interchange traffic between Denver and Chicago
running on this line, struggling to compete with a stronger and better
constructed Union Pacific system.
By 1964, the Rock Island
began attempts to merge with Union Pacific, and restructure railroads
west of the Mississippi River. This merger was eventually denied, and
Rock Island turned its last profit in 1965. In the mid-1970s, the
railroad was in serious decline. The railroad received loans to attempt
to fix slow orders, received new equipment and turn a profit. By 1978,
the railroad came close to profit, but creditors were lobbying for a
complete shutdown of the Rock Island. During the fall of 1979, a strike
crippled the railroad, and by January of 1980, the entire system was
ordered to be shut down and liquidated. Many of the lines and equipment
were scrapped. Profitable sections of railroad were prepared for
sale. The route between Omaha and Hallam was abandoned. The route between Jansen and Hallam was sold to Mid States Port
Authority in 1984, and began operations under Union Pacific Railroad the same
year. Today, UP owns the surviving part of this line and operates it as the Hallam Subdivision. The line through Lincoln is now the Rock Island Trail, and plans are being made to extend the trail to US-77. East of Lincoln, a small segment is now the Dave Murdock Trail, and the Platte River Bridge is now part of the Mopac Trail. The remainder of this line is now privately owned and abandoned.
Located near South Bend, this large deck girder bridge carries the Mopac Trail (former Rock Island) across the Platte River. The first bridge at this location was completed in 1889. This bridge was replaced with a deck plate girder structure at some point. This deck plate girder structure consisted of 30 spans of different sizes. The present bridge appears to have been constructed at two different times. The end spans appear to be older, utilizing rivets and missing an American Bridge Company plaque. It is believed that these spans were probably built around 1920. The center spans of the bridge utilize a welded design, and have missing Paxton-Vierling Steel Company plaques. These spans appear to have been constructed around 1970. The entire bridge is set onto concrete substructures. Due to flooding issues, several spans of the bridge were replaced in the 2000s with new piers and steel stringer spans, designed for trail use. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The author has ranked this bridge as being minimally significant, due to the newer age and alterations.
