MOSES LAKE - A propane tank truck flipped on its side after colliding with the Interstate 90 median Wednesday morning.

The incident caused westbound and eastbound lanes of I-90 to be shut down for about an hour, according to Washington State Patrol.

Seth Hayes, 20, Moses Lake, was driving in the right lane of I-90 when he swerved to the left to avoid a slow-moving car, according to state patrol reports.

The 2009 Strickland Propane tank truck entered the median and rolled onto its side.

Hayes was airlifted to Samaritan Hospital to be treated and released.

A small amount of gas was leaked from the truck, according to state trooper Trooper Rich Magnussen.

"Someone discovered that a valve on the back of the truck was loose. It was contained quickly," said Magnussen.

The incident is under investigation.
