The Lyman Viaduct is an infilled former railroad bridge in the US state of Connecticut in the area of the Colchester township . The Air Line Trail runs on the viaduct today . It has been on the National Register of Historic Places since 1986 . The trestle -style truss steel bridge was built over Dickinson Creek in 1873 . The wrought iron bridge was built by the Phoenix Iron Works for the Air Line Railroad. It led a single lane route and was 339 m (1112 ft) long and 42 m (137 ft) high. The Bachtal was later filled in for heavy goods traffic and in 1913 the framework was encased.
Passenger traffic on the Air Line route had its heyday in the 1880s and 90s, but the tortuous route and speed limits on the route did not prevail against the Shore Line Railway along the coast of Long Island Sound . At the beginning of the 20th century the viaduct was still used for freight and local passenger transport, but the increasingly heavier freight trains led to construction work in 1912. In order to support and strengthen the crossing of the valley, the valley was filled with sand and the framework was encased with slag. The railway line was badly damaged in a 1955 flood and the air line was abandoned in the 1960s.
The Air Line route was later reopened as the Air Line State Park Trail and along with the Rapallo Viaduct , the construction was added to the National Register of Historic Places in 1986 .
