Crews search for cause of large Nevada sink hole

A sink hole discovered in the median of Interstate 80 west of Reno forced the temporary closure of two travel lanes in both directions.

The California Department of Transportation says the sink hole is located about a half mile west of Donner Pass Road in Truckee.

The Reno Gazette-Journal reports all lanes were open Friday afternoon after crews finished filling it.

The cause of the sink hole is still unknown, but Caltrans spokeswoman Rochelle Jenkins says it was probably created by water moving underground near the highway.

The sink hole had encroached upon the fast lanes of both westbound and eastbound traffic, but so far there's no sign of stress or cracking of the highway that is the main route between Northern California and Nevada.

Traffic in both directions had been restricted to one lane through the area earlier Friday. KTNV
