This is a two lane, paved highway all the way. The road is well maintained. Snow may fall then melt in late September but the road is usually snow-free until October.
Time passes quickly when the scenery is superb.
You'll drive for miles without seeing another vehicle, a house, or town. The road then follows the glacier-fed Delta River for many miles. Several glaciers are visible on both sides of the highway, but the Worthington Glacier is my favorite place to stop and stretch my legs. The glacier's terminus is within a five-minute walk of the highway. I like walking on this hard-packed blue ice.
