In 1926, the original starting point of Route 66 was at East Jackson Boulevard and Lake Shore Drive.
Jackson Boulevard was the original Route 66, but it is now a one way street heading eastbound, towards Michigan Avenue and Lake Shore Drive.
As a result of changing two-way streets to one-way traffic, you can come into Chicago on the original Route 66, but you have to leave by way of Adams Street (one way westbound).
Adams Street begins at the entrance to the Art Institute of Chicago.
