The two right lanes of I-94 north/west at County K in Racine County have reopened after a tanker overturned around 6:00 AM Wednesday morning. 

A replacement tanker truck is on its way from Chicago and when it arrives on scene, the sodium bicarbonate will be off-loaded from the toppled tanker-trailer.

The left lane of both I-94 south and north will remain closed until the tanker can be cleared from the freeway.

The State Patrol says only a small amount of hazardous material from the tanker and diesel fuel from the tractor leaked out. The spill was contained quickly.

The condition of the driver is unknown.
