In 1869, the Burlington and Missouri River Railroad in Nebraska (BMRN) would continue constructing westwards from Pacific Junction, reaching milepost 12. The following year, a 17 mile extension from Oreapolis, Nebraska north to Omaha would be made, and an additional 48 miles to Lincoln would be constructed from milepost 12. A permanent bridge across the Missouri River at Plattsmouth would be completed in 1880. Since 1880, the BMRN had been controlled by stock by the same interests
that controlled the Chicago, Burlington & Quincy Railroad
(CB&Q). The CB&Q and associated ownership came in control or
constructed a large number of lines throughout Iowa and Nebraska. This route would serve as a piece of the planned Chicago to Denver mainline, which reached Denver in 1883. In 1885, the Omaha and South Western Railway constructed 4 miles of new railroad from Omaha, to South Omaha. In 1886, the Omaha and North Platte Railroad (O&NP) completed an additional 30 miles of railroad, extending from Omaha to Ashland, where it met the main line. The 4 miles constructed in 1885 were sold to the O&NP in 1887, and the O&NP sold to the BMRN in 1887. The BMRN was formally sold to the CB&Q in 1908, and CB&Q continued to operate these routes as parallel mainline, and a second track was added from Lincoln to Waverly in 1910, and Waverly to Ashland in 1918. In 1970, CB&Q merged with Northern Pacific Railway and Great Northern Railway
to form Burlington Northern Railroad (BN). BN merged with Atchison,
Topeka & Santa Fe Railway in 1996 to form BNSF Railway. BNSF continues to operate the Oreapolis-Omaha-Ashland line as the Omaha Subdivision, and the Pacific Junction to Lincoln segment as the Creston Subdivision.
Located near Ellison Street in Pacific Junction, this through plate girder bridge carries a former Chicago, Burlington & Quincy Railroad mainline over Pony Creek. The first bridge at this location was likely a timber pile trestle, constructed when the line was first built. During the early years of the 20th Century, the CB&Q invested significant capital into this line, upgrading bridges with steel and concrete substructures. The present bridge was constructed in 1909, reportedly using a span fabricated in 1905. Currently, the bridge consists of an 80-foot through plate girder span, set onto concrete abutments. The main span follows a standard design for the era, with two heavy plate girders, square girder ends and ballast deck floor constructed of numerous parallel I-beams placed transversely between the girders. The abutments also use a standard design, with sloped wing walls. In addition, tall concrete blocks were added to the abutments in 2019 to raise the bridge after unprecedented floods nearly destroyed the structure. An unknown contractor fabricated the superstructure, while it is unclear if the substructures were constructed by an unknown contractor or by company forces. Through plate girder spans were commonly used by railroads, as they were durable and easy to construct. Since the initial construction, the bridge has seen no significant alterations, and remains in regular use. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The author has ranked the bridge as being locally significant, due to the common design.
