About location

Joint Base Lewis–McChord has served as a military installation in the Puget Sound region since 2010. Created through the consolidation of Fort Lewis and McChord Air Force Base, it is one of the United States’ major joint military installations. Interstate 5 runs alongside the base and forms the principal north–south road through western Washington, linking the Tacoma area with Olympia and communities farther south. The base’s grounds combine developed service areas with woodland typical of the lowlands between Puget Sound and the Cascade Range. Its presence shapes this busy transport corridor and the communities that support military personnel and their families.
