David Williamson Flickwir (1852-1935) was a civil engineer and railroad engineering contractor. His company built one of the world's largest concrete bridges, the Tunkhannock Viaduct. [1]
David W. Flickwir was born in Philadelphia, Pennsylvania, on September 26, 1852, to Joseph Williamson Flickwir (1809-1899) and Rebecca Barton (1824-1907). He entered railroad work in 1871 as a rodman in an engineering corps for a railroad. [2] In 1875, Flickwir was an engineer for the construction of the buildings for the Centennial Exposition in Philadelphia. [2] An 1876 Philadelphia business directory lists Flickwir as a consulting civil engineer. [3]
In 1893, Flickwir married Charlotte Nalle (1856-1923) of Orange County, Virginia. Nalle died in October 1923. Flickwir remarried in May 1925 to Mildred A. Elder (1892-1991) who was the nursing superintendent at Roanoke Hospital (today Carilion Roanoke Memorial Hospital). [1]
In 1879, he was a construction engineer on the Shenandoah Valley Railroad. In 1881, he moved to Roanoke, Virginia. In 1883, he was made engineer and superintendent of the SVR. [2] In 1890, he was appointed general superintendent of the Eastern General Division of the Norfolk and Western Railroad, and served in that capacity until he resigned on February 1, 1895. In 1896, he started his own contracting firm, the Flickwir company. [2]
In 1908, Flickwir's company received a contract from the Delaware, Lackawanna & Western Railroad (DL&W) to build Section 3 of the Lackawanna Cut-off, a rail line that would run from northwestern New Jersey to northeastern Pennsylvania. The Flickwir company would build the line from mileposts 50.2 to 55.8, as measured from the DL&W's Hoboken Terminal, a stretch that required the construction of Wharton Fill, Roseville Tunnel, Colby Cut, and the eastern half of the mammoth Pequest Fill. During this project, Flickwir worked with Lincoln Bush, the Lackawanna's chief engineer. After the work wrapped up in late 1911, Bush left the railroad and joined Flickwir in a business partnership, Flickwir & Bush. [4] [5]
From 1912 to 1915, Flickwir & Bush built the DL&W's Tunkhannock Viaduct, a concrete deck arch bridge that spans the Tunkhannock Creek in Nicholson, Pennsylvania, in the United States, as part of the Nicholson Cutoff project. Measuring 2,375 feet (724 m) long and towering 240 feet (73 m) when measured from the creek bed (300 feet (91 m) from bedrock), it was the largest concrete structure in the world when completed in 1915 [6] and still merited "the title of largest concrete bridge in America, if not the world" 50 years later. [7]
In 1916, Flickwir was elected a director of the Norfolk and Western Railroad company succeeding Walter H. Taylor (1838-1916). [8]
In 1926, Flickwir joined the First National Exchange Bank of Roanoke.
By 1906, Flickwir was wealthy enough to commission a grand house in the Colonial Revival style. The house helped set architectural trends in the city: "The great history books on Roanoke all pay homage to this structure," said Kent Chrisman of the Roanoke Historical Society. In 2005, Jefferson College of Health Sciences renovated the house for use as its admissions and financial aid office and renamed it "Fralin House". [1] Over the 1920s and 1930s, he gave hundreds of thousands of dollars to the hospital, which dubbed him its "Greatest Benefactor". A 1925 building he funded, the Flickwir Memorial Unit, still stands. [1]
Flickwir died in 1935 after a short illness at age 83. [1]

The Erie Railroad was a railroad that operated in the northeastern United States, originally connecting New York City — more specifically Jersey City, New Jersey, where Erie's Pavonia Terminal, long demolished, used to stand — with Lake Erie, at Dunkirk, New York. It expanded west to Chicago with its 1865 merger with the former Atlantic and Great Western Railroad, also known as the New York, Pennsylvania and Ohio Railroad. Its mainline route proved influential in the development and economic growth of the Southern Tier of New York State, including cities such as Binghamton, Elmira, and Hornell. The Erie Railroad repair shops were located in Hornell and was Hornell's largest employer. Hornell was also where Erie's mainline split into two routes, one north to Buffalo and the other west to Chicago.
The Delaware, Lackawanna and Western Railroad was a U.S. Class 1 railroad that connected Buffalo, New York, and Hoboken, New Jersey, a distance of about 400 miles (640 km). Incorporated in Pennsylvania in 1853 primarily for the purpose of providing a connection between the anthracite coal fields of Pennsylvania's Coal Region and the large markets for coal in New York City, the railroad gradually expanded both East and West, eventually linking Buffalo with New York City. Like most coal-focused railroads in Northeastern Pennsylvania, the DL&W was profitable during the first half of the twentieth century, but its margins were gradually hurt by declining Pennsylvania coal traffic, especially following the 1959 Knox Mine Disaster and competition from trucks following the expansion of the Interstate Highway System in the 1960s and 1970s. In 1960, the DL&W merged with rival Erie Railroad to form the Erie Lackawanna Railroad that would be taken over by Conrail in 1976.
The Norfolk and Western Railway, commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America".
Frederick James Kimball was a civil engineer. He was an early president of the Norfolk and Western Railway and helped develop the Pocahontas coalfields in Virginia and West Virginia.
The Lackawanna Cut-Off was a rail line built by the Delaware, Lackawanna & Western Railroad (DL&W). Constructed from 1908 to 1911, the line was part of a 400-mile (640 km) main line between Hoboken, New Jersey, and Buffalo, New York. It ran west for 28.6 miles (46.0 km) from Port Morris Junction in Port Morris, New Jersey – near the south end of Lake Hopatcong, about 45 miles (72 km) west-northwest of New York City – to Slateford Junction in Slateford, Pennsylvania, near the Delaware Water Gap.
The Metro Rail Maintenance Yard or "South Park Terminal" houses Buffalo Metro Rail's cars in a train shed at the former Delaware, Lackawanna and Western Railroad terminal in the Cobblestone District of Buffalo, New York. The property is located at the southernmost fringe of the Central Business District. The station was built in 1917, and was designed to handle both steam trains and steamships. The storage and maintenance facility was converted to its present condition in 1982, following the demolition of the former main terminal concourse building "headhouse" of the DL&W Terminal in 1979.
Tunkhannock Creek Viaduct is a concrete deck arch bridge on the Nicholson Cutoff rail segment of the Norfolk Southern Railway Sunbury Line that spans Tunkhannock Creek in Nicholson, Pennsylvania, in the United States. Measuring 2,375 feet (724 m) long and towering 240 feet (73.15 m) when measured from the creek bed, it was the largest concrete structure in the world when completed in 1915 and still merited "the title of largest concrete bridge in America, if not the world" 50 years later.
The Paulinskill Viaduct, also known as the Hainesburg Viaduct, is a reinforced concrete railroad bridge that crosses the Paulins Kill in Knowlton Township, New Jersey. When completed in 1910, it was the largest reinforced concrete structure in the world.
The Delaware River Viaduct is a reinforced concrete railroad bridge across the Delaware River about 2 miles (3.2 km) south of the Delaware Water Gap that was built in 1908-10 as part of the Lackawanna Cut-Off rail line. It is the sister to the line's larger Paulinskill Viaduct. The Delaware River Viaduct also crosses Interstate 80 on the east side of the river and Slateford Road and the Lackawanna Railroad's "Old Road" on the west (Pennsylvania) side. Abandoned in 1983, it is part of an Amtrak proposal to introduce passenger service between Scranton, Pennsylvania and New York City, a distance of 135 miles (217 km) miles.
The Sunbury Line is a rail line that is owned and operated by Norfolk Southern Railway which in turn is owned by the Norfolk Southern Corporation. The line travels from Sunbury, Pennsylvania, to Binghamton, New York, connecting with Norfolk Southern's Southern Tier Line at Binghamton and Norfolk Southern's Buffalo Line at Sunbury.

William Haynes Truesdale (1851–1935) was an American railroad executive. He served as the president of the Delaware, Lackawanna and Western Railroad (DL&W) from 1899 to 1925.
Abraham Burton Cohen was an American civil engineer notable for his role in designing innovative and record-breaking concrete bridges such as the Delaware, Lackawanna and Western Railroad's Tunkhannock Viaduct, the world's largest concrete structure when completed. Cohen was an active member of the American Concrete Institute and earned ACI's Wason Medal for Most Meritorious Paper in 1927.
Roseville Tunnel is a 1,024-foot (312 m) two-track railroad tunnel on the Lackawanna Cut-Off in Byram Township, Sussex County, New Jersey. The tunnel is on a straight section of railroad between mileposts 51.6 and 51.8 (83 km), about 6 miles (9.7 km) west of Port Morris Junction. Operated from 1911 to 1979, it is undergoing work intended to return it to service no earlier than 2026.
Colby Cut is one of a number of cuts on the Lackawanna Cut-Off railroad line in northwest New Jersey. Located between approximately mileposts 51.8 and 52.3 in Byram Township, the cut was constructed between 1908 and 1911 by contractor David W. Flickwir. The cut, which was created by removing fill material obtained by blasting with dynamite or other methods, is 0.53 miles (0.64 km) long, has an average depth of 45 feet, and a maximum depth of 110 feet. The cut was the result of the removal of 462,342 cubic yards of fill material within this section.
