From the Wikipedia article
The Lewis and Clark National Historic Trail is a route across the United States commemorating the Lewis and Clark Expedition of 1804 to 1806. It is part of the National Trails System of the United States. It extends for some 4,900 miles (7,900 km) from Pittsburgh, Pennsylvania, to the mouth of the Columbia River near present-day Astoria, Oregon. It was originally established in 1978 as a 3,700-mile (6,000 km) trail following the historic outbound and inbound routes of the Lewis and Clark Expedition from Camp Dubois at Wood River, Illinois, to Oregon. In 2019, the trail was extended east to follow the expedition's 1803 preparatory journey from Pittsburgh to Wood River. The trail connects 16 states and many tribal lands.
