From the Chicago Pedestrian Plan: After the severe winters of 1978 and 1979, many of Chicago’s streets were converted from two-way to one-way to improve mobility during the winter and to allow plows to go through. However, two-way streets have many advantages over one-way streets. These ‘skinny streets’ reduce vehicle speeds and can also increase connectivity for all users by providing more ways to traverse the city’s grid. Skinny streets should be considered on all one-way streets that are wider than 30 feet.
