The Lincoln Highway was America’s first coast-to-coast highway. «Founded» by the Lincoln Highway Association in 1913, it was comprised of extant roads that were marked to show automobilists the way. In the early years, when the Lincoln Highway was being built, if any part of the road was paved at all, it was paved with gravel or macadam. The Portland Cement Association members and Lincoln Highway Association provided states with enough paving material to build one mile of concrete demonstration highway, out in the country, to demonstrate to motorists what a good road could be like. Called«Seedling Miles,» the demonstration sections were built out in the country, so if anyone wanted to see what the paved highway of the future would be like, they were forced to drive across lousy roads in order to experience the concrete Seedling Mile. Iowa had only one Seedling Mile, this one on Mount Vernon Road between Mount Vernon(home of Cornell College) and Cedar Rapids. Iowa has now signed the historic highway. You can follow the historic route from the Mississippi River at Clinton to the Missouri River at Council Bluffs by following the signs. As much as this section of highway is historic in nature, I only gave it four stars because you aren’t driving on the original concrete from 100 years ago. Linn County tore it up and replaced it a few years ago, but they did put up a monument. Originally, they placed a monument about 4−½ miles of east of here but after loud protest from Lincoln Highway enthusiasts, a duplicate marker was placed at the western portal of the Seedling Mile.(The original, misplaced tombstone marker, is located with a kiosk and reproduction bridge in Cedar Rapids, at Lincoln Heights Drive SE. It’s a street that was the original route of the Lincoln Highway. It’s a loop that avoided a steep hill that has since been cut down that Mount Vernon Road follows.) When you’re on this stretch of Mount Vernon Road, you are traveling a section of the most historic highway in the United States, celebrating its 100th anniversary in 2013.
