Stone arch on the former NYNH&H Canal Line, now the Farmington Canal Heritage Trail/East Coast Greenway, in the Hamden Plains section of Hamden. Presently located between a shopping center to the west and wetlands to the east.

The western side has been mostly filled in, though the top of the arch remains visible, while the east side remains intact. The arch appears to be constructed from brownstone and may be part of the original railroad construction in 1848-49.

It's unclear whether the arch was constructed as a farm underpass or across a watercourse. A 1949 aerial seems to show an unnamed tributary of the Mill River crossing beneath the railroad, but later images seem to show it being used as an underpass for an industrial site that previously occupied the area.
