Matlock Expressway
Wikisimpsons - The Simpsons Wiki
The Matlock Expressway is a freeway that connects the Central Business District, or otherwise known as the Downtown, to other regions of Springfield, most notably Evergreen Terrace. This freeway was Sideshow Bob's attempt to persuade the elderly to vote for him. Presumably, the freeway was demolished, as it does not appear in any other episode.
The Matlock Expressway also appears in the video game The Simpsons Hit & Run, but does not extend to Evergreen Terrace. Noticeably, this expressway has no major interchanges.
