Mapa de Anton Anderson Memorial Tunnel / Lugar

Linking the small community of Whittier to the wider road system, the Anton Anderson Memorial Tunnel is a remarkable feat of engineering and the longest highway tunnel in North America at 2.5 miles. Originally constructed during World War II for military access, it now serves as a vital connector to Whittier’s deep-water port and stunning backcountry access. Unique in its design, the tunnel operates as a single bore with bidirectional traffic managed by a timed signal system, ensuring safe passage through the rugged terrain of the Chugach Mountains. Travelers journeying through it are en route to breathtaking landscapes near Prince William Sound, where glaciers, wildlife, and kayaking adventures await. The tunnel’s seasonal accessibility and dramatic mountain surroundings make it not just a transit route, but a memorable part of any Southcentral Alaska trip.
