I’ve been doing a lot of research lately about Chicago in the late 1920’s, and it must have been an amazing time.Hundreds of miles of roads were being widened, hundreds more paved for the first time.The Chicago River was straightened south of Polk Street.Lake Shore Drive was extended all the way to Hollywood.South Water Street was reborn as the double-decked Wacker Drive.Michigan Avenue was widened, and the Michigan Avenue bridge turned the little country lane that was Pine Street into the Magnificent Mile.
