The bridge was constructed between 1906 and 1909 by the
Erie Railroad as part of its
Graham Line freight bypass, and was opened for service in January 1909. The trestle spans the valley for 3,200 feet (975 m) and is 193 feet (59 m) high at its highest point, making it the second-highest and -longest railroad trestle east of the
Mississippi River (after the 1889
Poughkeepsie Bridge of the New York, New Haven and Hartford Railroad, which is long and high). Apart from the valley below, the viaduct crosses two roads (Otterkill Road and Orrs Mills Road), the Moodna Creek, and the Erie Railroad's now-abandoned
Newburgh Branch. The open design of the trestle was used to reduce
wind resistance and is a major reason why the trestle is still in service today. ==Current use==
