Cambridge moved toward the railroad but kept a marker

At the east entrance to the Clay County Courthouse, a 1971 marker remembers Cambridge, a former settlement about three miles northeast of Henrietta. Cambridge became the county's main community and retail center in the early 1870s. It gained a post office in 1875 and an Army telegraph office the next year.

The town had a school, church, shops, hotel, and newspaper. Then the Fort Worth and Denver Railway reached Henrietta in 1882. Cambridge residents and businesses moved toward the tracks, and its post office closed. A second railroad later bypassed Cambridge for Henrietta, and the remaining residents left.

By 1991, the old townsite had been reduced to its cemetery. The marker stands at the courthouse rather than the vanished community, putting Cambridge back into Henrietta's everyday map.
