Via Jason Kottke, check out this post from Frumination.  The author figured out that if all the people who take New York’s subway into Manhatten every morning had to drive over the Brooklyn Bridge, the bridge would need–wait for it–228 lanes.

Given that the actual Brooklyn Bridge has only six lanes of car traffic, we might want to think about whether our own Port Mann needs 10.
