Last time I went out to Colorado I took interstate 80 and spent the night at a hotel somewhere in Nebraska. The morning that I left the hotel I noticed a sign that said limited access highway or something along those lines. This trail/dirt road followed along I-80 and the platte (I think) river for quite a distance and it seemed like there was an enter/exit point at each of the exits on the highway. I live in Ohio, but if this trail really exsists it seems like it would be fun to take a break from driving and ride a bit the next time I go to see my family in Denver.
