Called "Top of the World Highway" because much of its length runs above any wooded areas, it affords magnificent views. After crossing the Yukon on the small ferry, the road offers a series of constantly changing panoramic views: first, over Dawson City and the surrounding area; further along, over the Ogilvie Mountains, the valley of the Yukon and the Tintina Trench; finally, over the course of 90km skirting the crests, over mountains and valleys. Highway 9 joins the Taylor Highway (US Route 5) in Alaska.
