33rd Street, originally called Thirty-third Street Boulevard, is a long, wide, east–west parkway with a broad tree-shaded median strip. It is surrounded by 1920s-era "Daylight-styled" row houses with porches and small front yards. It was designed by the Frederick Law Olmsted Brothers firm, as part of their Baltimore Plan of 1904 and 1921 for establishing stream valley parks and connecting boulevards. The street is served by part of the MTA bus routes 3 and 22.
