The village had a station stop on the Maryland and Pennsylvania Railroad, at milepost 38.6, which served the farms within the area until it ceased passenger service in 1954 and ceased freight service in 1958. The post office for Street, Maryland is located in the village of Highland. The village was once home to Highland High School which later became Highland Elementary School.
