Midland Trail

One of the early 1910s trails mapped by the National Highways Association

• 1913: "Senators from Weber, Davis and Box Elder insisted that the route of the highway be designated through their counties in the bill and that be appropriated for the western outlet, of the Midland trail through Box Elder county." "The official route of the Midland trail through Utah as designated by the bill is from the terminus of the Colorado highway at the Utah state line near Grand Junction through Cisco and Thompson in Grand county, through Green River and Woodside in Emery county, through Price and Helper in Carbon county, through Kyune station, Colton. Soldier Summit. Thistle Junction, Spanish Fork. Springville, Provo, Pleasant Grove, American Fork and Lehi in Utah county, through Murray and Salt Lake in Salt Lake county, through Farmington and Kaysville in Davis county, through Ogden in Weber county and through Brigham City and Kelton in Box Elder county." This was not final: [3]
