TUPELO, Miss. (AP) — Cameron "Cam" Sholly, superintendent of the Natchez Trace Parkway, is leaving in September for a new job.

Sholly has been promoted to associate director for visitor and resource protection. The job is based in Washington.

An interim superintendent will be appointed until the position is filled on a full-time basis.

For the past three years, Sholly has managed a three-state national parkway corridor that traverses 41 county and municipal jurisdictions and was the eighth most visited national park in the country.

The 444-mile parkway runs from just south of Nashville to Natchez, Miss.

During his tenure, the parkway completed a multi-million dollar rehabilitation of the Meriwether Lewis death and burial site.

Sholly also oversaw completion of new resource management mapping system and completed the parkway's first business and operations plan.
