Lyman Viaduct was a railroad trestle built over Dickinson Creek in Colchester, Connecticut in 1873. It was a wrought iron post deck truss design and carried a single track. The viaduct was built by Phoenix Iron Works for the Air Line Railroad, and was 1,112 feet (339 m) long and 137 feet (42 m) high. The creek valley was filled in and the trestle was covered in 1913.[1]

Passenger train traffic peaked on the Air Line route in the 1880s and 1890s, but the winding course and speed limitations of the Air Line could not compete with the Shore Line Railway, a faster route following the shore of Long Island Sound. At the beginning of the 20th century the viaduct was still used for local passenger trains and freight trains, but the increasing weight requirements for freight trains led to a large construction project at the site beginning in 1912. To stabilize and strengthen the creek crossing, the valley was filled with sand and the trestle was covered with cinders. The rail line suffered major disruptions from flooding in 1955, and the Air Line was abandoned in the 1960s.[2]

The Air Line route later was converted to the Air Line State Park Trail.[2] The site was added to the National Register of Historic Places in 1986.[1]
