Berkeley is on Cook County's western border, 14 miles west of the Chicago Loop. With Interstates 290 and 294 forming its western and part of its southern boundary, and the Union Pacific Railroad (formerly the Chicago & North Western) and the large Proviso Railyard (a classification yard) to the north, Berkeley has ready access to the metropolitan region. Yet the transportation corridors that make Berkeley accessible to distant places also serve to separate the village from its nearest neighbors, creating a small-town atmosphere.
