U.S. 41 (Calumet Avenue) is closed in Hammond between Michigan Street and Sibley Street. This is the site of a bridge project that has been underway since early April with lane closures in place. Thursday, crews identified a pavement concern that needs to be addressed, requiring a complete closure at this location. It’s possible this closure could last through the end of May. INDOT will continue to update the public as details become available.
