What trails did people use while moving west?
One of the first trails into the West connected New England with land that is now Kentucky and Tennessee. A part of that trail, the National Road, is now known as US 40. The Oregon and the Mormon trail both went from St. Louis, Missouri to Fort Bridger, Wyoming. That this point the two trails split. The Mormon trail continued southwest to the Great Salt Lake. The Oregon trail continued northeast and over the Blue mountains into Oregon. The Santa Fe trail went along the Missouri River and into Colorado, from there it traveled Southwest to what is now New Mexico.
