Why doesn't Hope Street go through?

One of the little quirks about Downtown L.A. is that a major north-south street, Hope Street, stops at the Central Library. Yet Hope Street predates the library. The answer to the mystery, says Blogdowntown, lies in the story of the State Normal School, which used to occupy the site (known then as Normal Hill, an outcropping of Bunker Hill.) The teachers school later moved to Vermont Avenue, and its campus became the first location of UCLA, and now L.A. City College.
