A sinkhole on Interstate 80 has closed the No. 1 lane in both directions near Donner Pass Road in Truckee.
The sinkhole is in the center median.
Motorists can expect delays Aug. 23 heading toward the Sacramento and Bay areas as well as the Lake Tahoe-Reno region. Caltrans and a contractor are at the scene to assess the situation and then perform necessary repairs. There is no estimated time to complete emergency repairs and reopen the closed lanes.
The sinkhole developed during a paving operation early Friday morning. The sinkhole is estimated to be approximately 3 feet in diameter and more than 8-feet deep.
The cause is unknown at this time.
