It was replaced by a single, larger tunnel in 1954.

It was a small tunnel, barely large enough to walk within, but made, not natural.

They could see a large tunnel running away from the base of it.

Following the large tunnel on the other side, he came at last to the opening of the cave.

The narrow entrance had opened into a tunnel large enough for a man to stand up in.

The small passage widened into a larger tunnel and they were able to get to their feet.

At the back of the cave was a large tunnel that led off into the darkness.

They were on some kind of raised platform in a large tunnel.

It was the largest tunnel discovered so far at a detention center, officials said.

It also had a large tunnel, which allowed traffic to pass right beneath its center.
