TRUCKEE, Calif. (AP) - National Geographic is airing a 10-part documentary that captures the trials and triumphs of keeping Interstate 80 open through the winter over the Sierra Nevada's Donner Summit.

Truckee's Sierra Sun reports that "Hell on the Highway," running Wednesdays at 10 p.m., will star the treacherous winter of 2010-11 when more than 700 inches of snow fell - nearly 60 feet.

The documentary will focus on the tow truck operators, Caltrans employees and California Highway Patrol officers who fight snow every winter to keep open the 7,240-foot pass 30 miles southwest of Reno.

It also will focus on how important I-80 is not just to California but to the nation. Walmart sends 250 trucks over the pass each day.
