In 1887, the Chicago, Kansas & Nebraska Railway (CK&N)
constructed a 48-mile branch line, extending from Herington, Kansas
to Salina, Kansas. This route was one of several constructed in the
mid to late 1880s by the CK&N. The CK&N was almost exclusively
funded by the Chicago, Rock Island
& Pacific Railway (Rock Island). The Rock Island sought to expand
west through Nebraska, Kansas and Colorado, where they saw an entrance
to the Denver market as vital for the railroad. This route served as a branch line, mainly serving small towns. In 1891,
the CK&N failed to make a payment to the Rock Island. As a
result, the Rock Island took over ownership and operations entirely.
The Rock Island had constructed and acquired a large railroad network
throughout the Midwest. After World War II, the Rock Island struggled
to survive, proposing
mergers and deferring maintenance on their routes. The Rock Island struggled 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. A small segment of this line was sold to the Abilene & Smoky Valley Railroad, a tourist railroad. Today, the A&SV operates a segment between Abilene and Woodbine, while the remainder of the line is abandoned.
Located on the west side of Enterprise, this quadrangular lattice through truss bridge carries the Abilene & Smoky Valley Railroad across the Smoky Hill River. It is believed that this bridge was constructed in 1887. The bridge features a pair of standard 110-foot quadrangular lattice through truss spans, set onto stone piers abutments. The truss spans utilize a standard design for this era, including pedimented portal bracings with decorative cutouts, laced members and a lightweight floor. Various repairs have been made to the bridge since it was originally constructed, including adding the timber trestle approach to the west end. A concrete cap was added to the east abutment at some point in the 20th Century. The west pier was reconstructed with steel piles in 2014, and the remainder of the bridge was strengthened at this time.
The quadrangular lattice through truss design was relatively uncommon throughout the United States, with mainly railroads utilizing the design. The Chicago, Rock Island & Pacific Railway utilized this design as a standard design through the 1880s and 1890s, eventually replacing the standard design with a Warren design in the early 1900s. Many, if not all of these spans were fabricated by the Lassig Bridge & Iron Works, which supplied a handful of railroads with spans of this design. Overall, the bridge appears to be in fair condition, with some deterioration noted to the bridge. A walkway has been proposed to be added to the upstream side of the bridge for pedestrians. The author has ranked this bridge as being regionally significant, due to the age and truss design.
