Bridge Lifts Saturday After 8 A.M. From South Ashland To Lake Shore Drive

CHICAGO (CBS) -- The annual Chicago rite of spring means drivers might need to find an alternate route Saturday as bridge lifts for the boating season will take place.

Starting at 8 a.m. bridges will be going up and then lowering in succession along the Chicago River.

The boat run starts at South Ashland and works its way around to Lake Shore Drive.
