The Natchez Trace Parkway stretches through varied terrain for 444 miles from Nashville, Tennessee to Natchez, Mississippi. The National Parkway receives approximately fifteen million visitors each year, about six million of which are recreational visitors. Anecdotally, the number of bicyclists who use the Parkway is rising, in tourism, recreation, and commuting. In recent years there have been a number of crashes on the Parkway involving bicycles, four of which resulted in fatality. The Park staff has partnered with advocacy organizations in implementing safety interventions with bicycle-related signage and shared use lane markings. The Volpe Center conducted a study to evaluate the appropriateness and effectiveness of these interventions and make recommendations for the Park to continue their work in improving safety for bicyclists and other roadway users. This study looks primarily at the roadway corridor within the larger context of a safety campaign being conducted by staff and partners of Natchez Trace Parkway.
