Description 

New Haven Railroad Bridge Number 437, a stone arch bridge over Middle Haddam Road at milepost 28.18 of the former Air Line. The newer segment of road that is now CT Routes 17 and 66 replaced this segment of Middle Haddam Road of being a major route. An interesting feature of this bridge is that while the faces, southern wingwalls, and inside of the arch are constructed in granite, the northern wingwalls are built in brownstone. It is unknown if this is original or the result of a later modification.

Opened for use as park of the Air Line State Park Trail Portland section in 2018
