(La Porte County, IN) - At least one person was injured Friday morning in an accident involving multiple vehicles, including a semi-truck that wound up on its side in LaPorte County.

The accident happened after 9 a.m. (central time) at U.S. 20 and Indiana 39.

According to LaPorte County Police, three commercial motor vehicles and a passenger vehicle were involved in the collision.

Traffic was still moving in both directions on U.S. 20 but the westbound driving lane was closed just east of the intersection.

Police said the northbound lane of Indiana 39 at the intersection was also closed.  Motorists should expect to encounter delays near the intersection until the accident scene is cleared.

The semi-truck on its side came to rest on the shoulder beside the northbound lane of Indiana 39 while the heavily damaged passenger vehicle was also off the roadway just a short distance away.  The semi was pulling an open trailer filled with what appeared to be some type of aggregate material.

Some of that material spilled from the trailer onto the shoulder.  We'll provide further details once they're made available.
