CHICAGO (CBS) — All lanes of eastbound Interstate 94 have reopened in northwest Indiana, more than seven hours after two semi-trailer trucks crashed, spilling cocoa powder, lithium batteries, and other materials on the expressway.

After the collision, the second truck crashed into the concrete median barrier wall.
Both trucks also spilled their loads in the crash.
One of the trucks was loaded with various merchandise, including 100 pounds of lithium batteries, according to Indiana State Police.
The other truck was carrying food products, including cocoa powder.
Police there was no hazardous material in either truck, but when the batteries leaked onto the cocoa powder, it ignited small fires, which firefighters doused with water.
There were no injuries.
