Anton Anderson Memorial Tunnel (Whittier Tunnel)

The Anton Anderson Memorial Tunnel, also known as the Whittier Tunnel, is a remarkable feat of engineering that passes under Maynard Mountain, connecting Anchorage to Whittier. Stretching 2.5 miles (4 kilometers), it stands as one of the longest highway tunnels in North America, designed for both vehicles and trains. Built during World War II in the 1940s, the tunnel’s historical significance is matched by its impressive scale. Visitors can experience the unique sensation of driving through this long, dimly lit passage, emerging to stunning views on either side.
