The construction work near the curve by Sheep Creek on Thane Road is aimed at improving safety on the road.
The surface is being repaved, and a guardrail is being installed. The road is also being widened, but there are no plans to install a bike lane at this time.
There are no planned road closures, and the work should be finished by the end of the month.
Work has been scheduled around peak traffic times to avoid as much inconvenience as possible to drivers, said Jeremy Woodrow, communications officer for the Alaska Department of Transportation and Public Facilities.
