Lake Shore Drive (US-41)
Lake Shore Drive, around the Field Museum and Soldier Field, the speed limit drops to 35 mph, even though this is a newer, smoother roadway than the sections to the north and south. Most traffic flows safely at 55 mph here, and the Chicago Police are waiting for you behind the curves and overpasses.
WINTER ONLY: The speed limit on North Lake Shore Drive is lowered from 45 mph to 40 mph every winter, supposedly to protect vegetation from salt spray. The horticultural benefit is unproven, but it is a great moneymaker for Da Mayor, as you remember the higher limit last time you drove this same road.
