Union Street (Pasadena) is a street in Pasadena, California, United States, functioning as a connector through residential, commercial, and institutional neighborhoods. It runs east–west within the municipal grid and interfaces with multiple historic districts, transportation corridors, and civic institutions. The street's evolution reflects patterns associated with California urban growth, Los Angeles County, California suburbanization, and regional transportation planning.

History

During the Great Depression, municipal improvements and New Deal-era programs associated with agencies like the Public Works Administration and the Works Progress Administration affected nearby infrastructure, while post-World War II suburbanization driven by factors connected to Boeing and the Defense industry altered land use along arterial roads.
