The Road Into This Alaska City Is A One-Lane Tunnel That Cars Share With Trains - Jalopnik

The Anthony Anderson Tunnel, also known as the Whittier Tunnel, connects a highway in Alaska with the town of Whittier in a way few roadways do: it’s a one-lane, one-way tunnel shared by both cars and trains. At 2.5 miles long, it is described as the longest highway tunnel in the United States. The route leads to “The Town Under One Roof,” set between mountains and an arm of Prince William Sound that feeds into the North Pacific. The port stays ice-free, but the region is foggy and wet year-round. The U.S. Army also used the area to build a secret military base.
