The Simpsons: 10 Important Details That Are Almost Never Mentioned

Matt Groening and company have been relatively careful to not reveal too much concrete information about Springfield's geography, namely its precise place in the U.S. and especially the state it exists in.

Yet one of Springfield's more peculiar confirmed details is that the only road access out of the city is by way of a single bridge, Springfield Bridge, due to the overabundance of corruption in the city's operational infrastructure.

The bridge was even destroyed by a comet in season six's "Bart's Comet," though soon enough rebuilt.

While this is all obviously intended as a satire of what happens when the wrong people are put in charge of a city's money, it's fascinating that tens of thousands of people rely on a single bridge to travel in and out of the city.

Really, though, you're better off just thinking of Springfield as a geographically fluid location that isn't tethered to a totally fixed design or topography.
