Origins of name: This bridge spanning Buena Vista Street is modeled after the Glendale-Hyperion Bridge, a concrete arch-bridge viaduct built in 1928 that carries cars over the Los Angeles River, connecting Los Angeles’ Silver Lake neighborhood to Glendale.
Fictional back story: On Buena Vista Street, at least one business advertises its proximity to the bridge. “We’re under the bridge,” says an ad for Big Top Toys. The store’s entrance is, in fact, directly under the bridge.
What it really does: Carries the Disneyland Monorail track
I live super close to the original bridge - just drove on it yesterday. =) The Walt Disney Studios were located about one block from the beginning/top of the bridge from 1929 - 1939, on Hyperion Avenue. I’m sure this is why it’s replicated at Disneyland.
