According to the Kansas Department of Transportation, K-4 between K-43 and K-218 was closed just before noon, however the accident took place earlier in the morning. The highway is located between the communities of Herington and Hope. The Kansas Highway Patrol says the semi tanker involved in the accident was transporting liquid fertilizer and the spillage was near a waterway, which requires special procedures and precautions. Cleanup is expected to take several hours. The road remained closed as of 2:30 p.m.
