GARY, Ind. (AP) — State police say all lanes of Interstate 65 in northwestern Indiana are open again after two crashes closed them for eight hours.

State police Sgt. Chad Woody tells The Times of Munster (http://bit.ly/KhIxQp ) the first accident occurred at 2:36 a.m. Central time when a semi-tanker jack-knifed and struck another semi and a passenger vehicle near Gary. No one was injured.

Fifty minutes later, three semis approaching the back up from the earlier crash were involved in a rear-end accident. A female driver was taken to a hospital for treatment. Then one of the trucks caught on fire and the water used to extinguish the flames froze on the interstate.

All lanes of I-65 re-opened about 11 a.m.
