As is tradition, the Chicago River will be turned green for St. Patrick's Day on Saturday, March 11. Crews start the process in the morning, working from Columbus Drive to State Street, and the dye typically lasts a day or two (here's how they dye the river). After the water changes colors, it's off to Grant Park for the Chicago St. Patrick's Day Parade. Whether you decide to crowd onto the Riverwalk or buy a ticket to a rooftop event, here's where you can watch the St. Patrick's Day Chicago River dyeing.
