🌉 Lyman Viaduct

The Lyman Viaduct is a buried railroad trestle built over Dickinson Creek in Colchester, Connecticut, in 1873. Along with the nearby Rapallo Viaduct, it is one of the few surviving wrought iron railroad trestles from the first generation of such structures. It was built for the Boston and New York Air-Line Railroad, whose successor, the New York, New Haven and Hartford Railroad (NYNH&H), buried it in sand rather than replacing it with a stronger structure. The bridge was added to the National Register of Historic Places in 1986 since it is capable of providing detailed information about construction methods of the period. The bridge now carries the multi-use Air Line State Park Trail.
