Chenoweth and his brother Eli constructed 20 bridges, most of them covered, on four western Virginia turnpikes, notably on the Staunton-Parkersburg Turnpike system of western Virginia (now West Virginia).
Chenoweth was born, lived and died in Randolph County, West Virginia. He was an associate of Claudius Crozet, a noted civil engineer who oversaw the design and construction of Virginia's transportation infrastructure of turnpikes, canals, and roads with funding by the Virginia Board of Public Works and the General Assembly of Virginia during the 19th century prior to the American Civil War.
One of Chenoweth's best known surviving bridges is the Philippi Covered Bridge spanning the Tygart Valley River and carrying U.S. Route 250 in Philippi. The bridge is an outstanding example of a modified Burr truss bridge with two spans totaling 308 feet (94 m). It is also the only covered bridge in the United States currently incorporated into the national primary highway system.
Chenoweth was buried in the Beverly Cemetery.
