A rockslide closed the Seward Highway in both directions for about two hours Thursday morning.
The slide pushed debris and at least one huge boulder onto the highway just before seven o'clock this morning.
State Department of Transportation spokesperson Shannon McCarthy says an SUV hit the boulder, which alerted officials to the incident. McCarthy says local weather conditions could have triggered the slide.
"Anything that causes a freeze - thaw cycle can loosen material," McCarthy said.
McCarthy says slides are not unusual in the area, just south of Anchorage.
"This area, from Potter weigh station down to Indian, we do monitor throughout the year, but particularly in springtime, and other times, such as like after a seismic event or after high winds, for any material that may have become loose and may have fallen on to the roadway," McCarthy said.
Highway crews cleared the rocks away, and the highway opened up by nine a.m. According to Anchorage Police Department there were no injuries reported in the incident.
