New York, NY - Atlantic Avenue Tunnel
The Atlantic Avenue Tunnel, as it is now called, was built in seven months in 1844 by the Long Island Rail Road [Map] to relieve congestion in downtown Brooklyn. In time, it became sort of an urban legend, and many stories were
born about it and what uses some people may be putting it to. There
were also various attempts to find it throughout the years. In the early
'80s, Bob Diamond heard about it, and became captivated. [Images
from Bob Diamond] He made it his mission to locate it, and through
several years of research and physical work, he entered the tunnel.
Occasional tours of the tunnel are given by Diamond.

Pontifex by Chronic Logic
In Pontifex you design and test bridges. Pontifex uses a complex physics engine which allows the construction of many different types of bridges. Once your design is completed, you can test the strength of your bridge by sending a train across it. Depending on the quality of the bridge's design, the train will either pass over safely or plummet into the river below. The 3D engine lets you view your bridge from any angle, including a first-person "strapped to the front of the train" view. Many different levels are included, from simple to complex, and a level editor allows you to make your own levels to trade with others.
