Allen Park is home to the Uniroyal Giant Tire, the largest non-production tire scale model ever built, and one of the world's largest roadside attractions. Originally a Ferris wheel at the 1964 New York World's Fair, the structure was moved to Allen Park in 1966.

• I-75 runs through the southeast corner of Allen Park between Goddard Road and the Lincoln Park border.
• I-94 runs through the northern portion of Allen Park between Pelham Road and the Rouge River.
• M-39, Southfield Road, is an eight-lane boulevard that travels in a northwest–southeast direction between the Lincoln Park border and I-94. It becomes the Southfield Freeway and curves to the northeast after the I-94 interchange.

Allen Park was incorporated as a village in 1927, and as a city in 1957. It was named after Lewis Allen, a well-to-do lawyer and lumberman whose 276½ acres of land (primarily in Ecorse Township) included holdings in what are now Allen Park and Melvindale. Hubert Champaign (for whom Champaign Park is named) and Edward Pepper were two other early residents of the area.

In 1950 Allen Park did not include the part of the city directly west of Melvindale; that area was still part of Ecorse Township.
