The state Department of Transportation has closed one lane of Interstate 5 in each direction in DuPont for emergency repairs Thursday afternoon.
The inside lanes going north and south near the DuPont/Steilacoom interchange at milepost 119 are closed to fill a depression that has formed in the highway median.
The lanes will remain closed until the repairs are completed late Thursday night.
What caused the depression to form is under investigation.
