CHICAGO (CBS) — Today is the day the CTA shuts down the Red Line south of Roosevelt Road for five months of reconstruction.

The $425 million project will mean changes in the daily commute for thousands of riders.

For the first time since 1993, Red Line trains will operate over Green Line tracks into the Englewood terminal at 63rd/Ashland. Free express shuttle buses will run from the shuttered 95th, 87th, 79th and 69th Red Line stations to the Green Line Garfield station, where it will be free to board throughout the next five months. Another free shuttle will run between the Cermak/Chinatown station and Roosevelt.

But CTA President Forrest Claypool is urging you to study the rest of the transit map.

“The main people need to know is that if they come to the Red Line today they’ll have an express option to 55th Street or a local shuttle option but maybe, depending on where they live, there’s another easier, faster, more convenient option,” he said.

CTA also is increasing service on much of its South Side bus grid and Metra is adding stops on some of its Electric District trains.
