This trail takes you along a section of the Transcontinental Railroad, completed in 1869. It was the first railroad to span from the Eastern United States to the Western United States, connecting Council Bluffs, Iowa, to Sacramento, California. This trail, managed by the Bureau of Land Management, Salt Lake Field Office, is one of the few remaining original, historic railroad grades left that you can actually drive on.
While much of the original grade is closed off due to washouts, cave-ins, and broken bridges, you'll still get a good feel for it as you drive on and next to the original railroad grade.
While you could drive this road in a day, along with a stop in Promitory, Utah, to visit the historic Golden Spike National Park, there's also a great opportunity to take your time and camp along the trail or on Utah State Trust Land next to the Great Salt Lake.
