Its traditional boundaries are 27th Street on the east, 35th Street on the west, Wisconsin Avenue on the north, and the Menomonee Valley on the south. Traditionally an Irish-American enclave, it is now an ethnically diverse neighborhood. There is little in the way of commerce in Merrill Park, largely confined to the boundary streets, which are major arterials. Merrill Park was an early home to Milwaukee's Irish community. Many Irish settled in Merrill Park along with the rest of the west side of Milwaukee. The southern portion of the neighborhood was demolished in the 1950s in order to build Interstate 94.
