All lanes of Interstate 81 are back open in Botetourt County.

The right northbound lane was closed until just a half hour ago.

A truck driver lost control on the wet road around 6:00 p.m. near Buchanan.

He ran off the road and down a hillside, spilling his load of dish soap everywhere.

Some of it got into a nearby creek.

It shouldn't cause any major environmental damage.

11:45 p.m. Tuesday - All lanes are back open.

State Troopers say the driver of the truck lost control on wet roads. It's unclear how fast he was driving at this point.

Some of the dish soap spilled into a nearby creek.

The Botetourt County Sheriff's Department told people living in the area to keep farm animals away from the water, but deputies say the soap shouldn't cause any long-lasting environmental problems.

Crews will be out there for a few more hours cleaning up the boxes of soap that spilled out of the truck.
