In Lake County, the Indiana Department of Transportation reports northbound Interstate 65 at the I-80/94 interchange has reopened. I-65 northbound was closed at the Borman Expressway for several hours today after a semi-tanker hauling what officials described as hazardous materials overturned. No word at this time what those hazardous materials were. The lengthy closure was due to the fact that special crews had to be called in to move the semi. The Indiana Department of Transportation says a special crew had to offload the potentially dangerous material.
