CHEROKEE — Federal highway officials say they may have both a cost estimate and a repair timeline this week for the section of U.S. 441 in Cherokee destroyed in a landslide.

Engineers with the Federal Highway Administration continued their assessment Sunday of the highway, which goes through the Great Smoky Mountains National Park. As the link between Cherokee, N.C., and Gatlinburg, Tenn., it carries more than 2 million visitors annually.

Charles Sellars of the National Park Service said engineers may complete their assessment this week.

The landslide happened Wednesday morning about 9 miles north of Cherokee. Sellers said officials estimated 90,000 cubic yards of mud, rock and trees slid down a steep slope.

The area received more than 8 inches of rain over three days.
