Overturned commercial truck closes Parks Highway in both directions at Milepost 183

An overturned commercial truck closed the Parks Highway in both directions at Milepost 183 early Tuesday, according to Alaska 511 alerts from the state Department of Transportation and Public Facilities. The truck blocked both lanes of travel.

The Parks Highway is the main road route between Anchorage and Fairbanks. The department sent a high-importance alert to the Anchorage, Denali, Fairbanks and Mat-Su regions telling drivers to avoid the area. A second alert went to regions across the state, from Juneau to the Dalton Highway corridor.

The department's alert lists the closure as starting at 12:57 am and expected to last several hours, with an end time of 12:56 pm. A separate Alaska 511 traffic event, logged at 1:16 am, lists a planned end of 12:17 pm.

The Parks Highway carries local and commercial truck traffic year-round, and traffic grows each summer, according to 2018 department project documentation for the stretch between Mileposts 163 and 183.

Neither alert included information on injuries, the cause of the crash or the driver. Current road conditions are posted at Alaska 511.
