The Saturday before St. Patrick’s Day means green will be seen all around the city — including the Chicago River.
Here’s what you need to know if you plan to catch a parade or the river-dyeing process.
The dyeing process starts Saturday morning (usually at 10 a.m.) and stretches from Orleans Street almost three-quarters of a mile east to Columbus Drive. The task usually takes 45 minutes to complete. Spectators can watch along Upper Wacker Drive. The Riverwalk will be closed starting Friday night and reopen Sunday.

Bridges will be closed to spectators during river dyeing except for Orleans Street and Columbus and LaSalle drives, which will remain open to vehicles and pedestrians.
Want to take a ride on the newly tinted water? Depending on which direction the wind is blowing, the water can stay green for up to a few days. Chicago Water Taxi begins its seasonal service Saturday. Wendella, Chicago’s First Lady and Shoreline Sightseeing also offer a variety of tours.
That one time the river was dyed blue
A crew dyed the Chicago River blue in 2016 to celebrate the World Series champion Cubs on the day of the team’s victory parade and celebration.
What’s the weather forecast?
Saturday will be partly sunny but very windy — with gusts up to more than 45 mph at times — and highs in the mid-60s, according to the National Weather Service Chicago office.
When does the downtown St. Patrick’s Day Parade take place?

There is about a two-hour gap between when dyeing of the Chicago River begins and the parade — which is in its 70th year — steps off. Starting at 11 a.m., spectators can only access the parade route via Jackson Boulevard and Ida B. Wells Drive. All bags and purses will be checked at these entrances. Leave coolers, alcoholic beverages and water bottles at home. VIP seating is sold out.
