The Yellowstone Trail, completed in 1916, was the first transcontinental road stretching from Plymouth Rock, Massachusetts to Puget Sound, Wash.
While mired in a boggy pothole in South Dakota, J.W. Parmley envisioned a well-maintained road system stretching from coast to coast. He organized the Yellowstone Trail Association to construct it. Using steam-powered tractors, horse-drawn graders, shovels and picks, hundreds of people along the route began construction on the road in 1912 and completed it in 1915.
To publicize the road, on September 11, 1916 a relay from Plymouth Rock to Seattle took 121 hours, the fastest time ever clocked across the nation. Three cars were used in the Livingston to Missoula leg of the relay that came through Deer Lodge about 10 a.m. on September 15.
A 1910 Overland, like that was used during the race is on display at the Montana Auto Museum in the Old Montana Prison.
