Stone bridges such as this one allowed locals to cross small creeks and served as wash ways for early America transportation. Stone and stone masons were in abundant supply, and so making the bridges was very low-cost. These bridges tended to last a long time, and many are now historical landmarks.
Hunterdon County, New Jersey is known for these bridges, and the bridge in this photograph could certainly be in Hunterdon. Here is a link to the county's inventory of single-arch stone bridges.
