Still under development, this trail will run through 12 states when it’s completed—including Nebraska, where the completed trail will encompass 591 miles. The Great American Rail-Trail crosses from Iowa into Nebraska on the 3,000-foot cable-suspension Bob Kerrey Pedestrian Bridge over the Missouri River—connecting Omaha and Lincoln to the western, more rural, part of the state using one of the longest (219 miles) and most famous rail-trails in the country—the Cowboy Recreation and Nature Trail, known for offering a wildlife rich, authentic Old West experience.
