CHICAGO (STMW) - The CTA will operate special shuttle buses for people attending the 2011 Chicago Auto Show, and will provide service during all show hours on three regular bus routes.

The 2011 Chicago Auto Show — the largest and longest-running auto show in North America — runs from Friday through Sunday Feb. 20 at McCormick Place. Public show hours are 10 a.m. to 10 p.m. through Feb. 19, and 10 a.m. to 8 p.m. on Feb. 20, according to the auto show’s website.

Special auto show buses will shuttle visitors between Downtown ‘L’ lines and McCormick place on weekends and weekdays, according to a release from the CTA.

Red and Blue line riders can connect to the shuttle via Jackson Boulevard rail stations, the release said. Brown, Green, Orange and Pink line riders should get off at the Adams/Wabash station and walk one block south to Jackson. The buses will also stop at the Museum Campus (Columbus Drive and 11th Street) before running express to McCormick Place.
