PLAINFIELD, Ind.-- A pileup with more than 40 vehicles closed Interstate 70 in both directions about 20 miles west of Indianapolis.

Indiana State Police say eastbound lanes are now open on Interstate 70 west of Indianapolis.

Sgt. Rich Myers says the eastbound lanes reopened about 7:30 p.m., more than five hours after a pileup involving more than 30 vehicles.

Traffic no longer is being diverted at the Indiana 39 interchange at the 59 mile marker. Westbound lanes remain closed.

Westbound traffic is being routed onto Indiana 267 and eastbound traffic at Indiana 39.

Calder says the main crash occurred at the 55 mile marker, but a second crash involving at least two jackknifed semitrailer rigs occurred nearby.

A photo posted atwww.wishtv.com showed at least five rigs angled side-by side, each one completely blocking all lanes in one direction.

Meteorologist Brad Herold of the National Weather Service says snow was falling at the time of the crash. There's no immediate word on injuries.
