A tractor-trailer crash on I-84 is causing serious traffic problems in Orange County this morning.

The crash happened around 5:30 a.m. in the westbound lanes near mile marker 21.6 in Wallkill.

Officials say the truck slammed into a sign support structure, and the truck suffered major damage to the cab and the trailer.

Only one lane is open, and cleanup is expected to take a few more hours.

It is unknow if there are any injuries, or what caused the truck to hit the sign support structure.
