The Michigan Avenue Bridge in the 21st century is raised twice weekly in the spring and fall to allow tall craft to winter near the river and have summer moorings on Lake Michigan harbors. In the 19th century and into much the 20th century, such bridge raising or swiveling also facilitated commercial traffic through much of the year
