 Forty-sixth street at J Street was the turnaround point for the J Street Line making it one of the widest streets in East Sacramento.The lots between 38th and 47th Streets and bordered by J Street and Folsom Boulevard are among the largest in East Sacramento, creating the concentration of larger houses that gave rise to the area's name.Up until the Great Depression, the grand homes of the "Fab '40s" were considered to be the modern day equivalent of a suburban mansion.
