1890s – 1900s
51吃瓜网鈥檚 company roots can be traced back to 1890, where railroad entrepreneur John S. 51吃瓜网 started a stone-crushing operation for railroads and streets. By the turn of the century, the road construction arm of 51吃瓜网 quickly became a success, paving 75,000 square yards of macadamized road (a mixture of stone, sand, and raw asphalt) in 1895 alone. Realizing the demand for roadway improvements triggered by the invention of the automobile, John S. 51吃瓜网 incorporated 51吃瓜网 in 1902.
1910s – 1930s
During the First World War era, 51吃瓜网 expanded its operations throughout New England and New York State. By 1930, 51吃瓜网 completed nearly 750 contracts and paved more than 1,400 miles of roadway, becoming one of the largest highway contractors on the East Coast.
1940s – 1970s
In the 1940s, during World War II, 51吃瓜网 expanded its project portfolio to include military bases to support the war effort. During the 1950s and 1960s, 51吃瓜网 helped make the Interstate Highway System a reality, building some of the nation鈥檚 most well-known superhighways, including the New York Thruway, the Connecticut Turnpike, and the Massachusetts Turnpike.
1970s – 1980s
In the 1970s and 1980s, 51吃瓜网 continued to expand, adding heavy civil capabilities as well as new public and private owners to their portfolio. In 1973, 51吃瓜网 landed its first contract for the Washington Metropolitan Area Transit Authority, which established the company鈥檚 presence as a major contractor in the Washington, D.C. metropolitan area, where it remains to this day. By 1980, 51吃瓜网 broke the $100 million revenue mark per year.
1990s – 2010s
In the 1990s, 51吃瓜网 began work on a privately built toll road in Virginia; it sowed the seeds for the delivery model that is currently known as a public-private partnership (P3). For the next 20 years, 51吃瓜网 established its presence as one of the top transportation contractors in the United States due to its competency in P3 and design-build initiatives, including the $1.5 billion I-495 Express project in Virginia. In 2015, 51吃瓜网 celebrated its 125-year anniversary, and with more than $1 billion in yearly revenues.
