Geography Boynton and Oakwood Heights occupy the southernmost of the city of Detroit. It is the only area of the Detroit city limits that fall south of the River Rouge. Boynton is the southernmost neighborhood, stretching as far south as Outer Drive on the border with the city of Lincoln Park. The city of Melvindale is to the west, and the cities of Ecorse and River Rouge lie to the east. Interstate 75 (I-75) bisects the two neighborhoods north–south. Oakwood Heights is the smaller of the two neighborhoods and borders Melvindale to the south and the city of Dearborn to the northwest. The two neighborhoods are connected to the rest of the city of Detroit by two bridges across Interstate 75 and Fort Street (formerly known as U.S. Route 25) connecting to the neighborhood of Carbon Works, which lead to the neighborhoods of Springwells and Delray. Dix Avenue also crosses the river to connect Oakwood Heights to Dearborn. Oakwood Heights also connects to Fordson Island in the River Rouge via Riverside Drive. Fordson Island is part of the city of Dearborn and has no public access or residents. Despite the heavy industrialization, several parks exist within the area. Kemeny Park, located along Fort Street in between I-75, is the largest recreation facility. The park opened in 1957 and was named after local resident Charles Kemeny, who died in combat in World War II. The park closed in 2015 but was reopened in 2018 after a $9.5 million renovation—$2 million of which was donated by the nearby Marathon Petroleum
