Journalists Reginald and Lawrence Moore are shown above with the pilot car for a pro-motion to celebrate the opening of the highway from Duluth, MN to Glacier National Park. The car on the left appears to be a Nash, the other is an unknown make and the official press and photographers car is seen below.
The road is a transcontinental run of almost four thousand miles, runs through the US and Canada from Portland, Maine to Portland, Oregon. There is limited information online about the highway put it appears to be the second major highway built to cross the country and was finished in the 1920s. The first was the Lincoln highway which we will cover at another time.
