Chenoweth and his brother Eli constructed 20 bridges during the 1840s and 1850s, most of them covered, on four western Virginia turnpikes, notably on the Staunton-Parkersburg Turnpike system in what is now West Virginia.
Chenoweth was born, lived and died in Randolph County, Virginia (later 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 prior to the American Civil War (1860-1865).
One of Chenoweth's best known surviving bridges is the Philippi Covered Bridge (1852) 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, although it has been extensively reinforced and reconstructed.
Chenoweth was buried in the Beverly Cemetery.
