Patterson Viaductとは 意味・読み方・使い方

The Patterson Viaduct, heavily damaged by a flood in 1866, spanned the Patapsco River at Ilchester, Maryland. Built from May to December 1829, the viaduct was part of the Old Main Line of the Baltimore and Ohio Railroad. It was constructed in the first building phase of the railroad, which extended from Baltimore, Maryland to Ellicott's Mills. The Patterson, the third bridge built for the Baltimore and Ohio, was similar in construction to the Carrollton Viaduct. Designed by Caspar Wever, it was built under the supervision of John McCartney, one of his assistants. McCartney received the contract to build the Thomas Viaduct as a result of his successful completion of the Patterson contract.
