Section of Jackson Blvd. closed until April

June 1, 2009 (CHICAGO) The street was closed on Monday between Canal and Wacker. It's expected to remain closed until next April.

Crews will replace the viaduct at the Chicago River that spans Union Station's south passenger platforms and a number of railroad tracks.

The city's department of transportation says most of the work will be done at night to lessen the impact on train traffic.
